Tssp application for external works. Cement particle board - description, experience of the portal members on the use on the facade

What is a CSP? Why is it needed? Where and why is DSP used?

We will answer all questions in this article.

So what is a CSP?

CSP (cement particle board) is a new generation material. It is strong, waterproof and durable! Let's see why.

As the name implies, CSP is made from cement and wood chips. Cement resists fire well, and wood shavings do not allow the slab to crack in frost or heat.

In addition, cement-bonded particle boards have excellent heat and sound insulation qualities. It does this material universal for carrying out external and internal works in different climatic conditions. The material is just as easy to work with as conventional timber. But unlike wood, csp is reliably protected from damage by insects and rodents, and is practically not afraid of fungal formations.

Advantages of DSP

Environmental friendliness

The main chemical binder in DSP is the cement itself. This material does not contain any phenolic, formaldehyde and other toxic compounds.
Boards are made by pressing a mixture of wood chips, cement, minerals and water. Indeed, DSP is an environmentally friendly material.

fire safety

In case of fires in the premises DSP boards do not form smoke, do not emit toxic gases and vapors. Cement is generally considered a non-combustible material. AND,
if the DSP boards are compared with the well-known OSB, then the DSP clearly wins.

Biostability and moisture resistance

The composition of the DSP contains antiseptics that help to resist the effects of various fungi, beetles, rodents and other living creatures.
Biodamage of DSP boards is not observed even with prolonged exposure to moisture.

Frost resistance

Perhaps the most important advantage of CBPB is frost resistance, which expands the geography of the use of cement-bonded particle boards. Thus, the normative value of the decrease in bending strength after 50 cycles does not exceed 10%. In practice, the value of this indicator is lower. Long-term experience in the use of structures with TAMAK DSP in buildings for various purposes in Yakutia, Khanty-Mansiysk confirmed the high operational properties material.

Reliability

DSP TAMAK well tolerate changes in temperature and humidity levels for a long time. This ensures a wide geography of application and durability of structures.

DSP application

Construction and insulation of buildings

One of the most demanded types of work with the use of cement-bonded particle boards is the insulation of buildings. different type. V frame construction installation of cement-bonded particle boards allows you to perform two tasks at once. With their help, both the external and internal surfaces of the building are formed. Plates are attached directly to the frame-crate.

Usually, DSP boards with a thickness of 12-16 mm are used, which must be fixed to the crate. The size and material of the crate is best to choose strictly follow the manufacturer's recommendations. For this type of work, it is recommended to use mineral plates as a heater ( mineral wool). Between the plates you need to leave a small gap, no more than 10 mm. It must be insulated with elastic mastic or a sealing gasket. From above, such a gap must be closed, for example, with the same cuttings of the DSP.

Internal work with DSP

Cement particle board is completely safe for humans and environmentally friendly material. DSP boards are recommended for use in interior decoration premises of any type. Use such plates to quickly and efficiently align the wall. You can mount them on a wooden crate made of timber or a metal profile. To do this, use nails, screws and screws. After that, the plates can be faced, plastered, painted or carried out other work. This finish significantly improves the level fire safety.
DSPs are also excellent for forming internal partitions, especially when it comes to moisture-resistant partitions. If ordinary chipboard is well suited for an ordinary screen, then under conditions high humidity this stuff won't last long. In order to increase the service life of such a partition, it must be painted with a recommended moisture-resistant paint. Particular attention should be paid to the edges of the plate, they must be treated with a special moisture-repellent agent.

CSP floor and roof
The rule of good form is the use of DSP when laying the floor or the formation of a roofing cake instead of obsolete chipboard.

There is absolutely no need to change the technology. Usually the floor is arranged along logs with a section of 50x80 mm and a pitch of about 600 mm. For work of this type, more durable plates are used, with a thickness of 20 to 26 mm. With their help, you can lay the base under the floor, sf to form an underlying or leveling layer. DSP is also used for laying underfloor heating and clean floors with a front layer. Separately, it should be noted the possibility of laying a floor from a cement-bonded chipboard with a thickness of 24 and 26 mm directly on the ground. This allows you to build storage and utility rooms on bulk soil even at sub-zero temperatures. That is, the cost of repair and ancillary work is significantly reduced. Firstly, it is not necessary to select the right time and temperature, secondly, the installation of such a floor is carried out in a short time, and thirdly, with a minimum of financial costs, a full-fledged working room is obtained.

Concerning soft roof, then, despite the increased moisture resistance of the building material, it is necessary to strictly monitor the waterproofing. The main danger for any roof is water that has penetrated and accumulated inside. If the damage is not detected in time, then
the consequences can be very different. Therefore, the joints between the plates must be protected with strips of sheet material. After that, they are additionally reinforced with strips of protective roofing material. And only after that a protective roll coating is applied to the roof itself. But in general, the process of forming a base for a soft roof with the help of a DSP is practically no different from working with similar wood materials. Depending on the design of the building, slabs with a thickness of 16, 20 and 24 mm are used.

Outdoor work with DSP

Cement particle boards are often used in outdoor applications. The simplest example is sheathing metal doors. You can pick up and attach a plate of the required size even without prior preparation. Excess edges can be easily removed with a hand tool. Sheathing can be carried out both from the outside and from inside. This will significantly increase the sound and heat insulation of the room, as well as give the door fire-resistant qualities. One DSP slab 20 mm thick is capable of holding the flame for 50 minutes. It is recommended to use this material for fencing a balcony or loggia. Usually, asbestos-cement sheets are used for this purpose, but this material is very fragile. This complicates its installation and leads to a quick failure during operation. By using DSP for balcony railings, you get a strong and durable structure.

V Lately window sill boards began to be produced from CBPB. The size of such a board can be very different. Usually they are made directly on the construction site, depending on the size of the window. The minimum thickness of such a board is 10 mm, the maximum is 26 mm. This technology is characterized by the following advantages: low price, durable smooth surface, no joints, dimensional stability. When pouring the foundation, cement-bonded particle boards are increasingly used as formwork. This technology has proven itself in low-rise construction. Typically, slabs with a thickness of 12 to 26 mm are used, depending on the size of the foundation. In this case, the plates perform two functions at once. Firstly, their use can significantly reduce labor costs and terms of work, because. installation of this building material is as simple as possible. Secondly, if the outer part of the slab is painted with a special paint, then they will take on the function of vertical waterproofing. But the main thing is that the DSP is strong enough not to deform during pouring and hardening of the concrete mixture.

Cement particle board is a relatively new building material with a versatile scope. It has a completely natural base, DSP sheets do not burn, are not afraid of moisture, are resistant to most external influences and require minimal protective finishing. The reviews are mostly positive, the owners of private houses classify them as budget ones. The only significant limitation is the high specific gravity, on average it is 1300 kg / m3, which makes self-assembly difficult.

The material is shaped flat slabs with a dense and uniform structure of a gray-brown color. CBPB is based on cement and wood chips (65 and 24%, respectively), 8-8.5% of the volume of raw materials is water, the remaining 2.5% is hydration additives to reduce the moisture concentration in the final product (for example, aluminum sulfates). Harmful impurities are absent, the cement particle board does not contain asbestos, formaldehydes or phenols. At the same time, it is highly resistant to biological influences, the alkaline environment formed by the cement protects the chips from decay, fungus, insects and even rodents. For the same reason, he is not afraid of fire, despite natural wood.

Technical characteristics of DSP and their dimensions are regulated by GOST 26816-86. The main indicators include:

Density - in the range of 1100-1400 kg / m3, the standard value is 1300.
Humidity - 9±3%.
Water absorption by volume in 24 hours - no more than 16%.
Combustibility group - G1.
Bending strength, depending on the thickness of the plates - not less than 9-12 MPa, compressive strength - within 0.4.
Thermal conductivity coefficient - 0.26 W / m K.
Vapor permeability - 0.03 mg / m h Pa, which justifies the use of such boards indoors.
Deterioration of strength characteristics at 50 cycles of freezing and thawing - no more than 10%.

DSP has standard sizes: 2700 or 3200 mm - in length, 1200 or 1250 - in width, thickness varies from 8 to 40 mm. The surface of the plates can be smooth or embossed, the roughness of polished products is zero. Tolerance in length and width do not exceed ± 3 mm, in thickness - ± 1.4 for the thickest sheets. The reviews confirm the high geometric accuracy of the plates, their decorative and insulating properties are positively evaluated (noise absorption inside the premises reaches 30 dB).

Use in construction: pros and cons

The main limitation of the use of cement-bonded particle boards is the high specific gravity. With equal sizes, they lose to chipboard and other sheet building materials in this regard at least twice. The use of DSP automatically implies an increase in the load on the foundation and supporting structures, an increase in the requirements for the reliability of the frame and fasteners, and the difficulty in transporting them to the upper sections. One plate of medium thickness weighs at least 80 kg, installation by one person is impossible, as well as climbing to the second floor without scaffolding and winches.

Sawing and further processing are possible at home, but you should be prepared for the formation of dust. DSPs are abrasive materials with strength characteristics similar to dense wood, such purposes involve the use of tools with a high speed and hard working surfaces. On the other hand, according to the reviews, there are no problems with drilling, fastening and subsequent finishing, the edges when cutting in any case are neat.

In general, the advantages outweigh the disadvantages. The pluses include:

Ecological safety.
Versatility and multifunctionality.
Compliance with fire safety standards: flame does not spread over the surface of the DSP, the material does not emit smoke and toxic substances when exposed to high temperatures, the fire resistance limit is 50 min.
Long term maintenance-free operation, under normal conditions, durability reaches 50 years.
Geometrical accuracy of forms. These products are certified, the dimensional characteristics of cement particle boards are controlled by GOST. The stability of the forms is maintained throughout the entire service life, DSP is not afraid of UV or temperature extremes. Kinking is possible only when mounting on an uneven surface.
Independence from climatic conditions.
Good insulating properties, the scope of application includes multi-layer structures.
Resistant to moisture and decay.
Vapor permeability, allowing you to breathe.

The main criterion is the thickness of the plates, it is selected based on their intended purpose. In particular, the recommended limit for different building structures is, mm:

When installing formwork - 12-24.
For slabs for facade cladding and interior wall decoration - 10.12 and 16.
When erecting moisture-resistant partitions - 12 and 16.
The use of DSP as a window sill - from 24.
When using floor slabs (rough, bases for other building materials, leveling layer or finishing) - from 8 to 24.

The higher the expected loads (including humidity), the thicker the DSP is needed. At the same time, an increase in this dimensional characteristic leads to an inevitable increase in weight, which is not always acceptable. This also applies to the amount of material costs: prices for DSPs of various sizes, but the same in area, vary from 600 to 2500 rubles with a thickness of 8 and 36 mm, respectively.

The next factor to consider is the type of surface of the plates, the plaster fits equally well on both embossed and smooth varieties, but when painting, the use of the latter is preferable. Textured DSPs are optimal for internal decorative trim. Attention is drawn to the compliance of the characteristics of the GOST plate, in this regard it is better not to take risks and purchase products from trusted manufacturers. Products of Russian factories Tamak (Tambov), TsSP-Svir (St. Petersburg), Stropan (Omsk), ZAO MTI (Kostroma), Sterlitamak (Bashkorstan) have positive reviews. Their price offers are almost the same, the final cost is affected by the proximity of the warehouse and the volume of purchases.

Overview of reviews

“During the construction of a garage, a leveling cement-sand mixture was poured onto a compacted earthen floor, about 3-5 cm, after hardening, I placed sheets of DSP with a thickness of 26 mm on top. He gave a year to shrink, during this time the floor was exploited. I did not find deflections, breaks and places of decay of the material, the surface remained even, as a result, I covered it with tiles. There are no complaints about the quality."

Alexander, Moscow region.

“Four years ago I built a house outside the city in a frame way. A familiar builder praised this rather new material for our market, he decided to buy it for external and internal walls and gender. For the facade and rough flooring, I used cement-bonded particle boards 24 mm thick, for the lining from the inside and the ceiling 20 and 10 mm, respectively. The disadvantages include the difficulty of cutting and processing it - almost a special tool is required, a lot of dust is generated. The second drawback is related to the weight - it is impossible to install the DSP alone.

Pavel, Nizhny Novgorod.

“During the construction of the house, I used DSP with a thickness of 24 mm as a fixed formwork for the foundation. It turned out a big savings on the construction timber, when pouring concrete, they did not sag. Subsequently, he overlaid them with tiles, with minimum flow The adhesive holds well. I advise you to buy in bulk, at retail the cost of a sheet is at least 10% higher, and the leftovers on the farm will come in handy.

Igor, St. Petersburg.

“During the overhaul of the house, I used DSP boards instead of drywall for the installation of internal partitions and subflooring. Surprised by their quality, in the end they turned out perfect smooth walls. I puttyed only the seams, I chose wallpaper for decoration. The disadvantages include the weight and complexity of processing at home, because of the dust, the cut had to be carried out on the street.

Vadim, Moscow.

“I insulated the facade of the house with the help of mineral wool, for the exterior I decided to buy cement-bonded particle boards. Difficulties arose only when choosing a material for the frame, as a result, I settled on a wooden beam. There were no problems with fasteners; under the influence of moisture and sunlight in summer, the DSP does not lead and does not melt. It is worth paying attention to the seams, as they explained to me in a hardware store, when sheathing facades, they should not exceed 5-8 mm and must be sealed with special mastic.

The construction industry is one of the most actively developing today. Periodically, new technological solutions appear on the building materials market. One of such innovations is DSP boards, the sizes and prices of which have greatly pleased both specialists in this field and ordinary consumers. Today, together with HouseChief experts, we will try to figure out what is the uniqueness of this building material, what are its positive qualities, and whether it has disadvantages.

What is a CSP

The uniqueness of the sheet building material, which was briefly called CSP (cement-bonded particle board), lies in the fact that it was possible to combine seemingly incompatible components in its composition - Portland cement and crushed wood shavings. This became possible due to the introduction of special hydration additives that neutralize the harmful effects of the components included in the composition of the plates on each other. Modern manufacturers have learned how to make plates without the use of phenol and formaldehyde harmful to human health.

Technically, the process of manufacturing plates is as follows:

The raw mass is formed in a special drum, where wood chips, mineral components, Portland cement, and water are successively added.
The formation of the plate occurs in layers, while finely ground chips are located outside, and larger chips are inside the product, thereby ensuring its strength. The smoothness of the front layer is achieved due to small chips.
Moving along the conveyor line, the workpiece enters the hydraulic press, where it is molded under high pressure.

The ideal smooth surface allows even or even walls. If you veneer the house with panels and paint them in one of the pastel colors, you get a classic facade in, where leading role decorative strips will play, covering the joints between the panels.

Water-repellent properties have made products based on chips and indispensable for finishing wet rooms.

Specifications, application of DSP boards

The product density should be between 1100 and 1400 kg/m³ under normal humidity conditions.
Water absorption should not exceed 16%.
It is allowed to change linear dimensions at high humidity (6-12%) in width by no more than 2%, in length - by 0.3%.
The bending strength should be: 12 MPa - for panels with a thickness of 10, 12 and 16 mm, 10 MPa - for plates with a thickness of 24 mm and 9 MPa - for plates of 36 mm.
The strength of the plate under perpendicularly applied tensile loads must be at least 0.4 MPa.
Soundproof properties are 45 dB.
Thermal conductivity - 0.26 W / m × ° C.
According to GOST 7016-82, the value of the roughness level after factory grinding should not exceed 80 microns. For untreated slabs, this figure is 320 microns.
The material belongs to the group of low-combustible products (G1).
For dry rooms, the service life is 50 years or more.

frame construction

DSPs have proven themselves in the construction of frame-type houses. There are two options - the purchase of a ready-made house kit based on the DSP or independent construction walls, between which there is a mineral insulation. The slabs are fixed on a wooden or metal crate, while the frame is sewn around the perimeter, and then the House is cut out using frame technology using DSP

Article

For comparison with other materials, we propose to use such characteristics as:

fire safety;
ease of installation;
resistance to mold and disease;
reviews of builders;
feedback from residents and homeowners.

Fire safety and flammability class

In this parameter, DSPs are superior not only to polymeric insulation and PVC, but even to wood concrete. TsSP is assigned a flammability class - G1, that is, they are slow-burning. Due to the large proportion of cement, each of the chips is surrounded by a cement stone, so to start the pyrolysis process in wood close to the surface exposure to a temperature of 500 or more degrees for half an hour is necessary.

As soon as the thermal effect is eliminated, the pyrolysis process is quickly completed, because close contact of many chips is necessary for the start of a self-sustaining reaction.

If the temperature exceeds 700 degrees, and this effect lasts more than an hour, then the pyrolysis of the chips begins throughout the entire depth of the plate.

At this temperature, any building materials sharply lose strength, and concrete is completely destroyed. Therefore, after a fire of such force, the house cannot be repaired, unless the fire was local in nature and burned out only small plot Houses.

Even the start of the pyrolysis process does not lead to the release of particularly toxic substances, because the main components of pyrolysis gas (smoke) are:

nitrogen;
carbon dioxide;
carbon monoxide.

Only carbon monoxide is a serious danger, but, firstly, very little of it is released during pyrolysis, and secondly, during a fire, combustion occurs in conditions of lack of oxygen, so carbon monoxide is released everywhere in huge quantities.

Therefore, the DSP one of the safest in the fire plan of materials and is comparable to GKL and fiberboards. It is much safer than finishing from:

plywood;
boards;
wood concrete;
insulating fiberboards;
foams and plastics.

Ease of installation

Due to the high cement content of CSP much harder than most finishing materials.

The weight of thin sheets is 25-45 kg, so a minimum of 2 people are needed to work with them.

To work with thick sheets, 5-6 people are needed, because the mass of a sheet with a thickness of 26 mm exceeds 200 kg.

Cutting the material is also difficult, because you need to use high-speed circular saw and diamond-coated blade or carbide tipped.

Therefore, in terms of ease of installation, DSP is inferior to most finishing materials. After all, its weight, with equal dimensions and thickness, exceeds the mass of any other finishing material, including LSU and wood concrete.

Resistant to mold and disease

Due to the fact that the wood in the DSP does not have direct contact with air, it is less susceptible to mold and disease.

In addition, for products manufactured in accordance with the requirements of GOST, the chips are pre-soaked in a solution of lime or other reagents, increasing biological stability wood.

The use of DSP for the floor

When laying DSP on the floor along the logs, it is recommended to choose a thickness of products from 24 mm in order to ensure sufficient strength of the floor covering.

Fastening on lags

When working indoors, it is necessary to take preparatory measures - to close the holes in the base, if any, fix the logs, put insulation and vapor barrier material.

Preparatory work before laying the DSP on the floor

Fixation of the plates is carried out using self-tapping screws, while the screw with a countersunk head must be immersed in the body of the wooden beam by 20 mm. The result is a perfectly flat subfloor with excellent performance.

frame construction

DSPs have proven themselves in the construction of frame-type houses. There are two options - the purchase of a ready-made house kit from SIP panels based on DSP or self-construction of walls, between which there is a mineral insulation. The plates are fixed on a wooden or metal crate, while the frame is sewn around the perimeter, and then window and door openings are cut out. The elements of the crate are installed in increments of 60 cm so that the insulation material can be firmly fixed between them. Plates are taken with a thickness of 10–16 mm, fixed with galvanized screws.

Interior finishing works

The environmental safety of cement-bonded particle boards made it possible to use them as a full-fledged finishing material inside premises for any purpose. Due to its high moisture resistance, this material has significantly replaced drywall, which is not recommended for use on walls in wet areas.

Leveling the walls and floor in the bathroom

DSPs are used for effective leveling of walls and their subsequent finishing with decorative finishing materials. However, DSP in some interiors (loft, industrial, high-tech, and others), where a raw concrete texture is appropriate, is used to create accent surfaces and even to cover entire rooms.

The accent wall in the bedroom at the head of the bed is made of cement panels

The fastening of the plates depends on the thickness and dimensions of the sheets, and, accordingly, their weight. Heavy products are attached to the crate, and light ones - with the help of a special solution or mastic.

Production of SIP panels from CSP

CIP panels made of DSP are a three-layer material, where an insulation made of expanded polystyrene, basalt fiber or polyurethane foam (PPU) is fixed between the sheets.

Appearance of sandwich panels

A common distinguishing feature of the material is its high fire and environmental safety. The possibility of rapid construction of a private house and significant savings on finishing facade work.

The use of DSP for formwork in monolithic construction

There are a number of advantages of this type of fixed formwork device in the production of monolithic works:

Reduction installation work and the total period of construction of the object.
Surface ready for finishing.
High profitability of the construction of the facility as a whole.
Guaranteed to create a solid and reliable design.

Monolithic construction using fixed formwork from DSP

Mounting methods

DSP can be mounted different ways depending on the purpose for which they are used. When finishing or insulating buildings, they are attached to a crate made of a metal profile or wooden bars with self-tapping bolts or nails. The arrangement of fixed formwork also involves frame erection (given the large weight of the plates, it, like the crate when finishing the walls, must be strong enough). In addition, the slabs can be laid on logs (when installing the floor) or rafters (under the roofing). When interior decoration, they are also can be attached to the wall with mortar or mastic.

Preparing for DSP Coating

Before starting work on arranging a rough coating from DSP, the subfloor must be properly prepared. For example, in the case of laying material on wooden base old or rotten boards must be dismantled and replaced with new ones

It is important to close all the cracks with putty, and the wooden base is primed for better adhesion to the glue, on which the slab coating will be mounted.

If the installation will be carried out on a concrete base, then it should also be carefully inspected for damage and repaired if necessary. Also, if there are strong horizontal deviations, cement mixtures are leveled. In the case of laying DSP on the ground, a preliminary leveling of the surface is necessarily carried out - this can be done by pouring sand and gravel mix 20 cm thick and rammed it.

The process of building a gazebo with a DSP floor

The best option is to lay DSP boards on logs. In this case, if it is planned to install the base directly above the ground, the supports for the logs are installed on the ground, and hydro and thermal insulation is also laid. The distance between the supports can vary from 0.5 to 1 m - this figure depends on the thickness of the timber used for the logs.

Materials and tools that need to be prepared for working with DSP:

timber for lags (section 150x100 or 50x100 mm);
DSP boards in the required quantity;
antiseptic solution for timber;
sawing tool (for example, a hacksaw);
materials for waterproofing and insulation;
measuring instruments (tape measure, pencil);
fixing material;
drill.

How to paint DSP board

To give DSP boards an attractive appearance most in a simple way is coloring. After appropriate preparation of the surface, two coats of paint are applied with a roller or. Most often, in order to paint the DSP, they use:

Acrylic paints . This paint has good adhesion and is highly wear resistant. If financial possibilities allow, it is better to use paints that include a solvent, but also water-soluble facade acrylic paints, if properly applied, will last from 3 to 5 years.

latex paint . This coating is resistant to alkaline and mild acid solutions, easy to wash and mechanically clean with detergents. Besides. Painting works you can do it yourself, which will save a significant amount.

silicate paint . The use of this type of coating has high adhesion, their vapor permeability provides optimal conditions for air circulation, which prevents the appearance of mold and other fungi. The coating is not afraid of atmospheric influences and detergents, and the service life will satisfy even the highest requirements.

Before proceeding with the painting of DSP, it should be taken into account that the use of alkyd paints is undesirable, since cracking and peeling of the coating may occur upon direct contact with alkalis.

1 What are such plates made of, are additives needed?

DSP is a multi-component sheet building material, in the manufacturing process of which Portland cement and wood shavings are used. In addition, the composition of the plate includes special chemical additives that allow the base materials to coexist without any problems. Indeed, under normal conditions, wood is not friendly with cement, which provokes excessive moisture and the associated warping and decay of the material.

For the manufacture of CBPB, Portland cement and shavings are used.

The use of special additives (up to 2.5–3% of the total volume) eliminates the negative consequences of the proximity of wood and cement, giving the CBPB such beneficial features the first and second components, both heat resistance and fire resistance. Moreover, due to the percentage ratio - 24% of wood accounts for 65% of cement - the plate acquires other positive qualities: high strength, frost resistance, soundproofing properties, vapor permeability and complete disregard for the material by both insects and rodents.

In addition, at the same time, a wooden and cement board demonstrates such qualities as resistance to fungi, moisture resistance, resistance to temperature shrinkage and compatibility with most finishing materials, which is explained by enviable adhesion. At the same time, chemical additives in CSP do not belong to environmentally friendly harmful materials because they do not contain asbestos or formaldehyde.

Specifications of the DSP

In the manufacture of high-strength cement compositions are mixed with wood shavings of various fractions, water and a number of chemical reagents (for example, liquid glass or aluminum salts). Reacting with wood shavings, chemicals mineralize it, thereby increasing the strength and durability of the board.

Layering is the main quality of the boards, which guarantees their high quality and special strength. The formation of the slab structure occurs in such a way that large fractions of chips are located inside, and small ones are outside. After the preparation of the cement-chip mass, its layers are placed in special molds under the press, from where the finished multilayer DSP with a smooth surface on one side comes out.

DSP: specifications plates are such that it does not require the application of finishing putty. It is sufficient to paint the slabs after placement. In some cases it will be sufficient to apply a thin coat of primer before painting.

CSP floors laying nuances

In general, the installation of DSP boards is carried out in exactly the same way as the laying of OSB boards.

During the work, it is important to follow a few rules, and then the base of the floor will turn out to be of the highest quality: wooden beam for logs it is necessarily processed with compounds that prevent decay

Special compositions can be replaced with engine oil;

a wooden beam for a log must be treated with compounds that prevent rotting. Special compositions can be replaced with engine oil;

Wood preservatives

when installing plates on concrete screed for logs, you can use a beam of a smaller section - up to 50x50 mm. This will save usable space;
when installing the log, you should monitor their level - it must be strictly horizontal;
before installation, DSP boards are laid out on logs - this will allow you to determine which of them need to be trimmed if necessary;
glue must be well mixed before use;
Compensation gaps along the walls will allow avoiding deformation of the DSP base.

Another example of the use of DSP

DSP - the material is not bad enough, if you use it to create an even base. It is not difficult to work with him, but due to the large mass of sheets, it is better to get an assistant.

Mounting Features

Boards based on a cement-bonded mixture are easy to process. For cutting, you will need a hacksaw with fine teeth. Large teeth contribute to the formation of dust, makes the edges of the part uneven, so this tool is not suitable for sawing DSP.

When arranging a dry screed, concrete or wood flooring. It is also possible to lay sheets on a frame, the cells of which are pre-filled with insulating material (mineral wool, foam plastic, expanded clay, and another type of dry filler).

The plates are fixed with self-tapping screws or with the help of an adhesive mixture. The adhesive must be evenly distributed over the surface of the material with a notched trowel, leaving no gaps. This will help to avoid deformation of the material.

It is also important to generously fill the joints with adhesive to obtain a monolith. Self-tapping screws are screwed in at intervals of 35-50 cm

When facing the DSP of the outer walls of the building, an installation method is used that provides for the arrangement of the crate. Frame parts can be wooden or made of metal profiles. When choosing a tree, it is recommended to pre-treat it with an antiseptic solution to protect it from premature aging and microbiological processes.

To create a thermal protection of the dwelling, it is recommended to lay between the walls of the house and the DSP thermal insulation material. Preference should be given to basalt wool, which has a good rate of vapor permeability (the walls will breathe) and high resistance to moisture (low hygroscopicity will prevent moisture absorption into the layers of the heat insulator).

Fine finishing of slabs from a cement-bonded mixture provides for surface treatment with a primer, laying a reinforcing mesh and applying a layer decorative plaster. The facade is painted in a color that echoes other architectural elements of the exterior.

Arrangement of the floor with the help of DSP

Let's consider the arrangement of the floor from the DSP on the logs using the example of a balcony.

Step 1. A layer of insulation is laid under the logs. Logs are installed parallel to the walls at a distance of about 30-40 cm from each other.

Logs installed on top of the insulation

Step 2 Cross bars are installed, crates are being created. Wooden blocks are connected to each other with the help of metal corners and self-tapping screws.

Cross bars are installed, the crate is ready

Step 3 The space between the lags is filled with insulating material.

Insulation laying

Step 4 DSP boards the right sizes stacked across the longitudinal lag. The width of the piece of material should be slightly less than the width of the balcony (by 5-10 mm).

Laying DSP boards

Step 5 The plates are fastened with self-tapping screws on the logs. The gaps between the DSP boards are sealed with adhesive.

DSP in the process of creating the foundation

Cement- and chip-based slabs can be used to create formwork that aids in pouring foundations. The thickness of the material depends on the required dimensions of the foundation and ranges from 16 to 26 mm.

Strengths of CSP formwork.

Simplicity in the installation of plates by an order of magnitude reduces labor costs and reduces the time of work, thus reducing the cost of the process of pouring the foundation. On the outside you can apply a special paint, after which it will acquire the properties of vertical waterproofing. Due to the high strength of the plates, the formwork is resistant to deformation during pouring and drying of the concrete solution.

The versatility of DSP allows the use of this material in the construction of frame-based housing, for leveling floor and wall coverings, as well as during the installation of soft roofs in buildings of any type. CSP floor slab gets good reviews from builders all over the world due to its high quality material and excellent performance.

Cement particle board floor application

The main advantages of CSP are high strength and durability.

The use of building materials consists in laying finished panels on various types of bases:

a flat surface of a wooden or cement floor;
wooden logs installed at regular intervals.

On the surface of the plates can be glued ceramic tile, lay flooring, as well as lay laminate or parquet. The properties of the material are preserved for decades, subject to the installation technology.

Scope of application of DSP boards

As mentioned above, DSP boards, the use of which ensures high mechanical strength of the structures being created, are widely used in construction, repair and finishing works ah, in particular:

When making formwork foundations and other monolithic reinforced structures. The use of DSP greatly simplifies the installation process, in addition, this design prevents concrete leakage and ensures the formation of smooth side walls that do not require subsequent plastering.
For wall cladding and construction . In most cases, DSP sheets are attached to a pre-mounted metal or wooden frame. The thickness of the sheets in this case is from 8 to 12 mm. For fastening, self-tapping screws are most often used, it is also possible to use screws or nails as fasteners. In some cases, when leveling walls, special adhesive polymer mixtures can be used.
The use of DSP floor slabs provides high mechanical strength, as well as high rates of heat, hydro and sound insulation. The thickness of the material is selected based on the existing loads and the distance between the lags, however, the use of DSP boards with a thickness of less than 14 mm is not recommended.
Application for facade at home allows not only to significantly reduce the time of work on outdoor decoration, but also provides high-quality waterproofing of the main walls. Another advantage is that when using DSP, the characteristics of the material allow you to create various types of ventilated facades. As for the thickness of the sheet, for outdoor work it can vary from 12 to 14 mm.

Plate production

The production of DSP consists of the following steps:

Aluminum, liquid glass, various salts are part of aqueous solutions that are loaded into special mixers.
Mineralization of raw materials occurs with the gradual introduction of wood shavings into these solutions, consisting of different-sized fractional inclusions.
Then cement and a little water are introduced into the composition.
The mass is thoroughly mixed to obtain a homogeneous consistency, sent under a powerful press.
The output is thin, but strong, with a smooth surface product.

The smooth surface of the plate is obtained due to the special distribution of chips in its structure - larger fragments are inside the product, and small ones are on the surface. In the production of DSPs, there are no voids in them. Another advantage is that the product is not subject to additional leveling, but can be immediately used for the manufacture of a subfloor and serve as a high-quality, even base for laminate, tile and other types of topcoat.

DSP production technology

From the name itself it becomes clear that the main components of this material are cement (65%) and wood chips (24%). All this is mixed with water (8.5%), and various additives are added to the resulting mixture to improve the technical characteristics of the plate (2.5%).

Two types of chip material are used in the production process of DSP boards. They differ in size: small and medium. The plate itself has a three-layer structure, so medium-sized chips are poured into the second layer, and small chips into the first and third. The production process itself takes place in the following sequence.

Chips are mixed with hydration additives.
Cement grade M500 is added to the resulting mixture.
Water pours in.
The solution is thoroughly mixed until a homogeneous mass is obtained.
The first layer with small chips is poured into the mold.
The second layer with medium-sized chips.
And the third layer.
Pressing is in progress.
After that, the semi-finished material is heated to +90C for eight hours.
Then, within 13-15 days, it dries in natural conditions.
After that, depending on the batch, it is either polished or simply stored.

Cement particle board applications in construction

DSP is a cement-bonded particle board, and the name fully reflects the composition of this material. DSPs are made from a mixture, the components of which are wood chips and cement compositions.

What is DSP and OSB? What is the difference?

The composition of the building material includes:

wood chips with fractions of various sizes - 24%;
water - 8.5%;
special additives - 2.5%;
Portland cement - 65%.

DSP boards for outdoor use

The production process is quite simple - DSP is done as follows.

Special mixers are loaded with special aqueous solutions, which include various salts, liquid glass and aluminum.
Further, wood shavings with fractions are gradually added to these solutions. different sizes- mineralization of raw materials occurs.
Cement is added to the resulting composition and a little more water is added.
The mass is subjected to thorough mixing until a homogeneous mass and then goes under a powerful press.

The result of this production chain is the finished cement particle board, which is quite thin and has a smooth surface. A large amount of cement in the composition allows you to create a fairly durable material. By the way, inside the plate, the chips have b O Larger dimensions than outside, due to which the smoothness of the surface is achieved finished material. DSP does not need to be further leveled after laying, making the material excellent for creating a rough floor covering for laminate, tile and other types of finishes. Also, voids are not formed inside the DSP during production.

Cement particle board production

On a note! Wood shavings are also used as a raw material for chipboard production, fiberboard and OSB boards. The technologies for the production of these materials are somewhat similar to the technology for producing CSP boards.

Comparative table of performance characteristics of wood-based materials

DSP boards are widely used in construction. They can be used to decorate the facade walls of houses, they are used to create various partitions inside the premises. The material is suitable for use in restoration purposes and for interior finishing work. At the same time, it is suitable for apartments and private houses.

DSPs are used in construction for many purposes.

DSP plate is characterized by high environmental friendliness, as it is created from natural natural materials and practically does not contain additional chemical ingredients. That is why the stove is recommended for use both in residential premises and in production.

Cement particle board (DSP)

The use of cement particle board is an opportunity to abandon the laborious pouring of a cement screed to create a base. Building material allows you to reduce labor costs and spend less money from the budget planned for leveling the floors for laying the finish coating.

Processing rules for sawing and drilling DSP boards

Like it or not, CSP is a concrete stone filled with shavings (wood filler). Therefore, when the question is raised, how to process this type of material, one cannot mention a hand tool. Cutting and drilling can only be carried out with an electric tool.

At the same time, it is better not to use a jigsaw, although some craftsmen manage to cut plates of small thickness with such a tool. You just have to change the file often - every 5-7 m. Therefore, the optimal solution is a disc cutting tool.

The easiest way to cut DSP is with a circular saw with a diamond blade.

As for the disk, there are two options:

Diamond coated disc with cut out segments. This disc is used for dry cutting. Here you can use discs for cutting stone, concrete or brick - they all work.
Pobedite-coated discs for cutting wood. DSP is not the most durable material in terms of comparison with stone, so such a tool will cope with it.

As for power tools, most often craftsmen use a grinder or a circular saw (parquet).

Attention! It is easier to cut slabs with a DSP circular saw because the power tool has a support bar. It is she who allows you to clearly orient the disk in a perpendicular plane to the sheet, and as the final result - an even cut of the material

DSP slabs can be cut with a grinder with a cutting diamond disc installed on it

As for drilling holes in slabs, either metal drills or drills are used for this.

Types and characteristics

There are 3 types of DSP:

fibrolite- heat-insulating material based on long-fiber shavings (“wood wool”). Soft, easy to process, resistant to biological factors;
wood concrete- made from sawdust and small chips. It has a wide range of applications (thermal insulation, decoration, material for wall partitions, etc.);
xylolite(slab and cast). It has high strength, thermal insulation qualities and a wide range of color solutions used as a floor covering.

Due to their water absorption, the plates increase in size, so a gap is required when installing between them.

Kinds

There are three types of DSPs. Studies of the material showed with accuracy that each of them does not lose its valuable properties even in the process of multiple cycles of a significant increase in temperature and subsequent defrosting.

Resistance to fire and especially humid environment, negative biological factors was also confirmed. But each type of plate has its own characteristics, consisting in the method of production, the difference source materials, characteristics of the finished product and scope. Among the types you can specify.

1. Fiber mat. Its basis is the so-called wood wool, which is a long-fiber shaving. The composition also includes inorganic binders.

Wood tapes obtained on special machines are impregnated with solutions of calcium chloride and liquid glass. Raw materials pressed in molds are subsequently dried. The thickness of such plates can reach 150 mm, but there are a number of much thinner parameters.

These building elements, characterized by considerable strength, are excellent for thermal insulation. Similar material is also used as acoustic.

It is easy to process and soft, because of this, it is in demand for multifaceted repairs, as well as works on the reconstruction of various structures. During construction operations with plates, due to their low weight, lifting equipment is not required; therefore, their use is very economical.

2. Arbolit. It is classified as lightweight concrete and contains small shavings, sawdust, reeds or rice straw. The most high-quality plates of this variety are made from wood chips.

If the basis of the composition is wood shavings, then the material is usually called wood concrete, if sawdust - sawdust concrete. The two types mentioned have somewhat reduced performance compared to the first one mentioned above.

They are heavier, denser and subject to unpleasant deformations, but also cost somewhat less. The scope of arbolite is quite wide. But basically it is in demand as a material for low-rise private construction, it is especially popular in the manufacture of wall partitions, as well as for decoration and thermal insulation.

3. Xylolite is most commonly known in the application as a coating DSP for floor. Plates, similar to those previously described, are made of wood waste, differing from other types of production technology. On sale, the presented assortment pleases with a variety of colors.

The material is distinguished by excellent thermal insulation qualities and increased strength. It does not burn in an open fire, but only gradually chars; even when boiling, it does not soak in water and is slightly thermally conductive; has an enviable elasticity and is hard as a stone, but at the same time it is easily processed like a tree: it is drilled, planed and sawn. In application, in addition to the above, it is excellent as a sheathing for stone, covering stairs, window sills, roofs.

An important characteristic is the weight of the DSP board. Such indicators are simply necessary to know during construction and other works.

The specified data is very useful in the transportation of goods and at the time of installation work. The mass of one module directly depends on the thickness and, knowing this indicator, it is easy to calculate it. After all, for every 10 mm there is a tiled weight of approximately 54 kg.

Installation work than sawing DSP

You should not try to cut the DSP with a hacksaw - this is a thankless task, the process is long, and the result leaves much to be desired. You can use a jigsaw or grinder.

Article

Among slabs and sheet materials used for finishing and constructing partitions and various design elements, cement-bonded particle board or DSP cannot be ignored. Of course, in its popularity it is inferior to drywall, but, as practice shows, it modern world the place is located. Most often, the DSP slab is used by builders as a formwork. It is even, with good strength, plus - with its help, it is much faster to assemble formwork than from boards.

Many may doubt that the use of DSP is advisable for the construction of formwork. After all, it can be replaced, for example, by metal or plywood, which, moreover, were in use. Probably, it is true, but a plate with a thickness of 24-26 mm can withstand quite serious loads. In addition, if you install a fixed formwork using cement-bonded material, then, in fact, you will get a ready-made finished foundation or another structural element building. And this is a big plus in many situations.

In addition, it is necessary to take into account the conditions in which the room to be finished will be operated. For example, if this is a gym, then there can be no talk of any drywall. He just can't take the ball. And the DSP boards will hold up. They can be used for strapping and sheathing frame houses. Better than this material for this value today is not found. A plus is the ability not only to paint the cement-bonded material, but also to use it as a finish. Fortunately, manufacturers today offer a huge assortment with design under different materials as shown in the photo above.

DSP production technology

Chips are mixed with hydration additives.
Cement grade M500 is added to the resulting mixture.
Water pours in.
The solution is thoroughly mixed until a homogeneous mass is obtained.
The first layer with small chips is poured into the mold.
The second layer with medium-sized chips.
And the third layer.
Pressing is in progress.
After that, the semi-finished material is heated to +90C for eight hours.
Then, within 13-15 days, it dries in natural conditions.
After that, depending on the batch, it is either polished or simply stored.

Specifications

The fact that this is a durable material is understandable, because it contains a cement component. But it is also moisture resistant due to the use of hydration components. Plus, DSP boards have an excellent bearing capacity, which cannot be said about plasterboard or plywood. But a lot will depend on the parameters of the plate.

As for the width, it is standard - 1.2 m. But the thickness and length are sizes that vary in a fairly large range. As for the length, the manufacturer can cut it to any size if the order is large. But there are also standard values: 2.7; 3.0; 3.2 and 3.6 m.

As for the thickness, here is a fairly decent range: from 8 to 40 mm. Accordingly, the weight of the product will increase with increasing thickness. For example, a plate 2.7 m long and 8 mm thick weighs 35 kg. With a thickness of 40 mm, the weight will increase to 176 kg.

With a DSP length of 3.2 m and a thickness of 8 mm, its mass will be 41 kg. With the same length and thickness of 24 mm, the weight will be 124 kg.

There are no rounded edges and no chamfers in the design of CSP boards. The edges are straight and well cut, so there should be no problems with buttboards and fit. They do not need to be treated with antiseptic compounds before finishing, because during the manufacturing process, an antiseptic is added to the raw solution.

Other technical characteristics according to GOST:

Withstands high sub-zero temperatures. In this case, the defrosting process can occur up to 50 times. After that, the strength of the plates is reduced by only 10%.
The error on the outer plane is 0.8 mm.
The difference in the lengths of the diagonals can be 0.2%. It is practically no more than 5 mm for a length of 2.7 m.
Thickness error (permissible) no more than 0.8 mm. This is for unpolished material, for sanded 0.3 mm.
Water absorption is 16%, while during the day at high humidity the plate should not increase in size by more than 2%.
Withstanding tensile loads - 0.4 MPa, bending 9-12 MPa, depending on the thickness of the product. The thicker, the less it can withstand bending loads.

Manufacturers today offer two types of cement-bonded material that differ from each other quality characteristics. These are TsSP-1 and TsSP-2. The first one is better.

There is an opinion that plates of this type are inferior to drywall in many positions. You should not compare these two materials, they have different purposes and different applications. The above examples confirm this. Of course, the DSP has its drawbacks, which we will talk about.

Compared to drywall, cement-bonded particle boards cost almost twice as much. But GKL cannot be used for exterior decoration, and it is better not to sheathe a frame house with it.
The weight of each slab can be daunting, especially those over 16mm thick. You cannot work with them alone. Under them, you will have to build a strong and reliable frame. Yes, and the foundation will have to be strengthened if they are used for sheathing a frame structure.
In addition, the cement component gives the material increased strength, so that it is difficult to process it. Therefore, pruning must be carried out with a grinder or manual circular saw, while using not a simple cutting tool, but a diamond one.
The frame has already been mentioned, but it must be added that drywall profiles are not suitable here, especially when it comes to external finishing with DSP boards. A standard steel profile is required here.
When cutting plates, a large amount of dust is released, so this operation should only be done outdoors.
