CSP cooker application. Cement particle boards: properties and characteristics, applications, feedback from builders and home owners. Harmonious union: CSP panels panels for exterior decoration of the house

The first enterprises for the production of cement-bonded particle boards (CSP) were opened in the USSR at the end of the eighties of the last century, and many of them are still functioning. Cement and particle boards are not as popular as plywood, drywall or OSB, but they are universal material with a wide range of applications and high technical and operational characteristics. Members of the FORUMHOUSE portal are aware of all the advantages of DSP and actively use them, including on the facades of their houses.

Cement particle board - raw material base, manufacturing method, technical characteristics

One of the main advantages of these plates is natural composition- they do not contain formaldehydes and other aggressive chemicals released in environment during operation. Products different industries may differ in the composition of mineral additives, but the quantitative proportion of each group of substances used is unchanged:

  • Binder (Portland cement m500, GOST 10178-85) - 65%;
  • wood shavings – 24 %;
  • Water - 8.5%;
  • Hydration (mineralizing) additives - 2.5%.

DSP is a composite material made from a mixture of cement and smooth, thin wood chips. conifers. Since wood contains sugars and other substances that adversely affect cement and impede the formation of a monolithic structure, mineralizing additives are used to neutralize them. It can be calcium chloride, aluminum sulfate, aluminum sulfate, aluminum chloride, sodium silicates and others. The chips are processed with reagents, mixed with cement until a homogeneous mass is formed, after which it is sent for molding. To increase strength and obtain a smooth and uniform surface, the plates are formed from several layers, which differ in chip size and location. Most often there are three layers - the middle one, from coarser and larger chips, the outer ones - from smaller ones. Some industries form a chip-cement carpet of four layers, but the principle is the same - large fractions inside. The formed plates are pressed under a pressure of 1.8-2.0 MPa, after which they are subjected to heat treatment in the hardening chamber (8 hours at 50-80⁰С, humidity 50-60%). The parameters of the finished plates must comply with GOST 26816-86, there is also a European standard - EN 634-2.

The plates have a lot of physical and technical characteristics that will say little to the average consumer, who is mostly interested in
does it burn DSP plate so let's look at the main ones:

According to the regulations, the plates can be either 1250 mm or 1200 mm wide. The first option is outdated, although many enterprises, especially the "mastodons" of the industry, still produce slabs of this width. Length: two main sizes are common - either 2700 mm or 3200, but there are options for 3000 mm each, and the necessary parameters can be made to order. With a lot of advantages, the plates have a significant drawback - due to raw material base they get quite heavy. The thinnest slab, 8x1250x3200 mm, will weigh about 36 kg, and a 40 mm thick slab with the same dimensions will already weigh 185 kg. Therefore, when working with slabs, an assistant is usually required to unload a large number- equipment, and the restriction on the use on the facade is a height of more than three floors. But this material is used in almost all construction areas, depending on the thickness:

  • Internal wall cladding - 8-12 mm;
  • Interior partitions- 8-20 mm;
  • Roof systems, facade cladding - 10-16 mm;
  • Draft floor (overlapping, floating screed) - 16-26 mm;
  • Formwork - 14-26 mm;
  • Enclosing structures during construction frame houses- 10-40 mm.

DSP plate: application for outdoor work

One of the options for using DSP is a facing screen in ventilated facade systems. It turns out a smooth, resistant to external influences surface, completely ready for finishing. Since when installing plates it is mandatory expansion joint(6-8 mm, at least 4 mm), most often such sheathing is combined with half-timbered trim. It is also possible to paint the canvas with facade paints, like one of our users.

I have foam house, DSP outside and inside. Outside, it is painted with facade water-based emulsion on sheets, it holds up perfectly, on the inside, wallpaper on DSP - everything is fine. Together, it’s really possible to hang, a slab is sawn by a grinder, with a disk on a stone.

Technology DSP installation on the facade - standard: crate made of wooden beam or metal guides, with a step between the racks of 600-625 mm (binding to the width of the plate). Between the insulation and the DSP, there must be ventilation gap not less than 40 mm. The plates are attached to the crate with self-tapping screws, it is recommended to use galvanized or anodized ones, since black ones, even if the caps are putty, can eventually give rusty spots even after several layers of paint. Holes are pre-drilled under the screws in the slabs, if the screws are ordinary, countersinking is performed - a chamfer is selected in the upper part of the hole so that the self-tapping screw is recessed into the slab. When using self-tapping screws, the installation process is simplified.

Since DSP is quite heavy and to some extent fragile material, it is necessary to observe certain standard rules fasteners given by a member of our portal.

For DSP as facade material you need to remember about linear changes in geometry, with changes in humidity and temperature. They are there, like everyone else. board material. To resolve the issue with competent application and lack of further negative consequences, it is necessary to observe the installation technology.

  • Fastening step along the edges of the plate - 300 mm;
  • Indent from the edge - 16 mm;
  • Fastening pitch in the middle of the plate - 400 mm;
  • Fastening corners (against chipping) - at a distance of 40 mm along the long and short sides.

Expansion joints can be left open, closed with flashings or decorative overlays (faux timber) or sealed special formulations(when finishing with plasters). If the sealing of the seams is not planned, and the facing cake does not include insulation, before installing the plates, the racks are protected from moisture (special impregnations or insulating tapes).

Portal member Andrey Pavlovets used DSP with imitation fachwerk for building cladding country house and baths and is completely satisfied with my choice.

Andrey Pavlovets FORUMHOUSE user

For 12 years, the house and the bathhouse have already been standing - everything is sheathed with DSP, and the house had to be sheathed alone, due to the lack of assistants. To make it easier to work, I sawed the plate into squares of 1200x1200 mm, folding the sheets in a pile, then drilled and inserted fasteners. Sheathed on the old lining, so small gaps for ventilation remained. And the cake is as follows: outer layer - CSP - 10 mm, lining - 20 mm, glassine, crate - 25 mm, mineral wool- 100 mm, film (vapor barrier), air - 50 mm, crate - 25 mm, drywall, finish (wallpaper).

After installation, the walls were painted with two layers of water-based facade paint, a roller, the seams were closed with planed overlays. edged board, painted in dark light. The layout of the overlays was chosen taking into account the seams of the cladding. Although no primer was used, over the years the paint has not peeled off, and the house has not lost original view. However, if you follow the technology, preparation (priming) is an obligatory stage of work, and you should not neglect its implementation.

Cement - chipboard is also used for sheathing carcasses, as enclosing structures.

Cement particle boards (abbreviation DSP) are called whole class building materials used for various purposes.

They are made from wood shavings, high-quality cement and various additives that give cement-bonded particle boards the necessary characteristics.

  • what is DSP and how they are used in construction;
  • how they differ from other materials containing chips and cement;
  • what documents regulate the properties of cement particle boards;
  • what characteristics does the DSP have, and what types of this material are;
  • how DSPs are used and whether they are harmful to health;
  • how to determine a quality plate.

You will also find out what advantages and disadvantages cement-bonded particle boards have in comparison with other types of finishing materials and what builders and owners / residents of houses and apartments say about them.

Despite the fact that the term cement-bonded particle board (the material is shown in the photo) can be applied to many types of building materials, in world practice this name has been fixed only for panels and blocks, meeting the requirements of GOST 26816-86 which you can find.

Therefore, in the name of a building material manufactured according to this standard, the GOST number is always indicated. This applies both to Russian products and to plates officially supplied to Russia from abroad.

Nevertheless, conventionally, products of approximately comparable size can be attributed to DSP from:

  • chip concrete (Chip concrete);
  • fiber-reinforced concrete (Fibrolit).

Technical and other characteristics of the DSP

The main technical and other characteristics that distinguish cement and chip sheets from others include:

  • dimensions (length, width, thickness);
  • composition (percentage of components);
  • strength;
  • vapor permeability and water resistance;
  • density and weight;
  • thermal conductivity;
  • surface smoothness;
  • price;
  • processing and installation methods.

Standard sheet sizes

Standard sheet sizes are prescribed in GOST 26816-86 and are:

  • length 320 and 360 cm;
  • width 120 and 125 cm;
  • thickness 8–40 mm in 2 mm increments.

The remaining dimensions do not comply with GOST, but due to the high popularity, many enterprises producing cement-bonded particle boards do not neglect them either.

However, even with the observance of the manufacturing technology and full compliance with the characteristics, these plates cannot be called manufactured according to state standard due to size difference.

Tolerances these dimensions depend on the brand and constitute for:

  1. TsSP-1 in length and width ± 3 mm, in thickness ± 0.6–1.4 (depending on size).
  2. TsSP-2 in length and width ± 5 mm, in thickness ± 0.8–1.6 mm (depending on size).

Compound

The composition of the mortar from which blocks of wood chips and cement are made is not prescribed in GOST, however, most manufacturers adhere to the following proportions:

  • cement M500 - 65%;
  • wood shavings (types of shavings) various sizes and forms - 25–28%;
  • additives (lime, aluminum sulfate, liquid glass, etc.) 2–5%.

This composition provides a balance between strength, including stiffness, and thermal insulation properties.

If it is necessary to increase the strength of the product, then use more cement, and to reduce thermal conductivity, increase the percentage wood waste or select the most efficient chip shape.

By changing the composition and quantity of additives, regulate the ability to absorb water and resistance to frost. After all, what more water absorbed into the wood inside the slab, the more the cement stone will be damaged. Initially due to swelling, then due to the transformation of the liquid into ice, in which the volume of water increases by 11%.

Elasticity and bending strength most of all depend on the length and shape of the chips, as well as compliance with the technology of processing wood waste before introducing them into the solution.

Technology Disruption processing will not only reduce the strength of the concrete stone due to the sugars contained in the wood, but also increase absorbency shavings.

Use of incorrect reagents or strong increase their quantity can lead to a decrease in the vapor permeability of the DSP, which will make the boards unsuitable for use in breathing houses.

Strength

The tensile strength of cement particle board is low, so it cannot be used as a material that can withstand a nail or self-tapping screw with any load. However, according to this parameter, the DSP outnumbers most finishing materials, yielding only to glass-magnesite sheet (GML), so it can withstand a hanging picture, clock or even a shelf with light dishes.

In terms of bending strength, DSP also surpasses most finishing materials, second only to LSU.

All types of strength depend on:

  • chip length and shape;
  • proper processing of wood waste;
  • cement quality;
  • plate drying method.

Therefore, a material manufactured in accordance with the requirements of GOST has more high rates strength.

Vapor permeability and water resistance

One of the important properties is water resistance, which describes the ability of the material to retain its original moisture content even after immersion in water for a day.

According to this parameter, CSP is comparable to other wood-containing materials and surpasses LSU. Therefore, under normal conditions, when the material is installed vertically and it rains obliquely, water absorption is small, and it will take 10-100 hours to evaporate, depending on the duration of precipitation. In this regard, this material is quite moisture resistant.

Even if frost hits immediately after a heavy and long rain, the depth of the layer damaged by freezing water will not exceed a few hundredths of a millimeter.

In terms of vapor permeability, DSP is comparable to clay bricks and slightly inferior to wood. The reasons are in the porous structure of cement stone, as well as wood shavings. So, the vapor permeability of the chips along the fibers is 0.3 mg / (m h Pa), and the same concrete parameter is 0.03 mg / (m h Pa).

Due to the fact that part of the steam moves through the wood, the total vapor permeability coefficient is 0.08–0.1 mg/(m h Pa). At the same time, the vapor permeability of wood across the fibers is 0.06–0.08 mg/(m h Pa). Therefore, sheathing wooden house inside or outside the DSP, you will not impair its vapor permeability and do not deprive home of the main advantage - dry microclimate inside the rooms.

Other materials based on cement and wood waste have a similar vapor permeability value. After all, the process of movement of water vapor through the cement stone and wood fibers is the same, regardless of the name, purpose and thickness of the material.

Density and weight

Due to the high content of cement, the density of CSP is 1100–1400 kg/m 3 , which is comparable to:

  • solid wood plywood;
  • plasterboard sheets (GKL) that meet the requirements of GOST;
  • fiber cement boards.

Therefore, the weight of a plate with a thickness of 8 mm is 38–45 kg, the weight of a DSP sheet of 10 mm, 12 mm or 20 mm, respectively, is greater, and the weight of a plate with a thickness of 40 mm can exceed 200 kg.

This makes it difficult to use DSP on the upper floors if it is not possible to deliver it to the top by a crane or an electric hoist. In addition, thick sheets hard to mount on the ceiling, because this will require a team of several people and a powerful overlap.

The large mass also limits the use of this material for insulation. wooden floors, after all, very powerful overlaps are needed.

Thermal conductivity

This parameter describes the ability of the material transfer thermal energy through yourself, so the smaller it is, the lower the heat loss will be. The thermal conductivity of cement-bonded particle boards TsSP-1 and TsSP-2 GOST 26816-86 is 0.26 W / (m ° C). This is comparable to materials such as:

  • tuff with a density of 1200 kg / m 3 - 0.27 W / (m ° C);
  • expanded clay concrete with a density of 1000 kg / m 3 - 0.27 W / (m ° C);
  • foam concrete and aerated concrete with a density of 800 kg / m 3 - 0.21 W / (m ° C).

For comparison, we present the thermal conductivity of various structural and insulating materials.

Surface smoothness

Plates TsSP-1 and TsSP-2 come in several types - with a polished or unpolished surface. Difference between these types of products in acceptable roughness.

Unpolished have a smooth, but less smooth surface. The allowable roughness size for them is 0.3 mm.

For polished slabs TsSP-1, the allowable roughness size is 0.08 mm, for TsSP-2 maximum size roughness is 0.1 mm.

To the touch, the polished TsSP-1 board resembles high-quality polished plywood, and TsSP-2 looks like high-quality GKL. Unsanded materials resemble ordinary plywood or chipboard (chipboard).

What is the price?

The price of cement particle boards depends on:

  • compliance with GOST;
  • plate type (TsSP-1 or TsSP-2);
  • processing quality (polished or unpolished);
  • sheet size and weight.

Material corresponding to GOST 26816-86 always costs more than what is made without regard to this document. To some extent indication GOST 26816-86 in the name of the building material is synonymous with quality, regardless of the place of manufacture of the plate. We have prepared a table that includes the most popular DSP manufacturers and their official dealers, as well as the price per sheet of their products:

Name of manufacturer or seller Board dimensions (length, width, thickness in mm) Cost in rubles Cities where production and main representative offices are located

3200x1250x241900

As can be seen from the table, the cost of wood cement boards or panels depends on their dimensions, sheet thickness and, accordingly, its weight, which we talked about earlier: for each thickness indicator - be it 8mm, 10mm, 12mm, 16mm, 18mm, 20mm, 24mm or any other, its own price will be set for sheet or per m2 of material.

In addition, an unpolished slab with a thickness of 10 mm or 12 mm will cost less than a polished one of similar dimensions.

Processing and installation methods

When installing a DSP, like any other finishing material, it often becomes necessary to give it some specific shape.

Unlike plywood, OSB and other similar materials, DSP cannot be cut with an electric jigsaw.

Cement stone quickly erases the teeth of the blade until they completely lose their cutting ability. Therefore, to cut this material it is desirable to use:

  • angle grinder (UShM, Bulgarian) with a disc for stone;
  • circular saw with a diamond blade.

DSP can also mill, using for this manual cutter or copier milling machine, as well as a nozzle with carbide tips. For drilling, you can use a drill with both conventional drills for metal, and with those in which the tip is made of tungsten carbide.

To attach a cement-bonded particle board to any base, nails and hardened metal screws are used. A full-length hole is drilled under the nails;

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. Thanks to big share cement, each of the chips is surrounded cement stone, That's why 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 a special toxic substances , because the main components of pyrolysis gas (smoke) are:

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

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.

When performing construction and finishing works most important aspect is the reliability and durability of the resulting structure, but not all materials provide such parameters. That's why great solution is a cement-bonded particle board with the necessary performance characteristics. Products have their own characteristics, which should be taken into account in order to achieve the best result.

Deciphering DSP - cement-bonded particle board. The products include the following components:

  • Portland cement high brand(from M400) - 65%.
  • Wood chips (most often coniferous) - at least 24% of the total mass.
  • Water without impurities - 8.5%.
  • Special mineral additives (sodium silicate, aluminum sulfate and others) - 2.5%.

The availability of the constituent cement-bonded particle boards determines their high popularity.

The product belongs to composite materials and has been known for quite a long time, which is confirmed by GOST 26816-86. For a long time it was unclaimed due to the wide variety of the construction market.

At the moment, the manufacture of the material is regulated by GOST 26816-2016. This regulation is based on the 1986 document and the European standards EN 634-1:1995 and EN 634-2:2007. Although the demand for products is increasing, due to the excellent quality and reasonable price, its availability remains rather low.

Material production

The plate manufacturing technology includes a number of successive stages:


Modern production is constantly developing, so it is possible to obtain DSP sheets with a minimum thickness of 6 mm without loss of properties.

Advantages and disadvantages

The material stands out among the rest with many advantages:


But the DSP plate also has disadvantages:


When buying, pay attention to the availability of safety certificates.

Types of cement particle boards

The panels have a similar composition and allow you to choose suitable material for specific situation:

The characteristics of xylolite and fibrolite are very different, therefore their purpose is different.

  • Xylolite. The base contains shavings and magnesia cement. It has high strength, so it can be used as a floor covering.
  • Fiberboard. For production, wood raw materials that have passed special treatment, and burnt magnesite. Portland cement is used as a binder. The resulting parts are soft and suitable for thermal insulation.
  • Arbolit. Quite a popular variety for outdoor and indoor use.

The use of new technologies made it possible to bring "Arbolit" to the leaders of sales

It is also customary to divide parts according to the area of ​​\u200b\u200buse, depending on the thickness. There are two brands of products: TsSP-1 and TsSP-2, which differ in parameters.

Specifications

Such facing material has the following properties:

  1. Bending strength. From 9 to 12 MPa. This indicator indicates that the laying place should be even. But the resistance to longitudinal deformation of the panels is high, which makes it possible to use them to strengthen load-bearing structures.
  2. Density. From 1200 to 1400 kg / m 3. Values ​​vary due to possible fluctuations in humidity.
  3. Vapor permeability. It is about 0.03 mg/(m·h·Pa). The presence of a porous structure does not prevent vapor exchange.
  4. Humidity level. Within 9%. If the manufacturing technology is fully observed, then with constant exposure to water during the day, the indicator changes by less than 2 times.
  5. Thermal conductivity. Coefficient - 0.26 W / (m K). If you sheathe a house with such material, then its energy efficiency will increase.

Extended table general characteristics cement particle boards

Sheet size:

  • width - 120 and 125 cm (standard);
  • length - 320 and 360 cm;
  • thickness - from 6 to 36 mm;
  • weight is due to dimensions: a panel 1200 * 3200 * 36 will have a mass of 195 kg.

There are other options, regulations allow you to make parts required dimensions.

Design parameters of the best-selling DSP models

Since the material is environmentally friendly and moisture resistant, the area where it can be used is quite extensive:

  1. Frame construction. In such a situation, dimensional parts should be used, because they reinforce bearing structures. Wall ceilings are entirely sheathed with slabs, the field of which is processed.
  2. Facade decoration. This is the most the best way if the climate of the area is high humidity and severe frosts. The panels are used when installing a system with additional ventilation: they are laid on the crate. Due to the fact that the products are polished or unpolished, they are left unlined or plastered.
  3. Internal work. Plates make wall and ceiling cladding. In larger processes, the material is used to equip the attic and subfloor.

Known trade marks, such as Tamak, produce a complete line of high quality cement boards for different types finishing and operation

Characteristics allow the use of chipboard cement panels almost everywhere, if appropriate. Although all the work can be done with your own hands, the dimensions and weight of the parts require the presence of an assistant.

DSP plate (cement particle board)- popular building and finishing material, consisting of wood chips, Portland cement, water and special additives that provide the necessary performance characteristics.

Plates are made by pressing. The result is strong sheets with flat surfaces and ends, which can significantly save time during their installation. This is a non-combustible material, so it is recommended for widespread use in construction.

DSP is used:

  • as a lining of columns, internal and outer skin walls, door trim
  • for the construction of moisture-resistant partitions and wall cladding of wet rooms
  • as a front covering for floors, ceilings, window sills, creating the basis for roofing
  • as fixed formwork for building foundations

Cement particle boards

Cement-bonded particle boards (DSP, CBPB, cement bonded particle board) - a building material with unique properties used in the technology of "dry installation". CBPB belongs to a generation of modern composite building materials with properties that combine the strength and durability of cement with the flexibility and ease of processing of wood. Universal technical DSP characteristics have already been fully appreciated all over the world.

Thanks to its high technical and quality characteristics plates have the widest range of applications and are able to facilitate the solution of a number of tasks that arise during construction and repair work, in interior and architectural projects. The use of cement-bonded particle boards can significantly reduce not only material and time costs for any construction and repair work and optimize operating costs finished building due to durability, thermal insulation properties and other useful qualities cement particle boards.

Cement-bonded particle board is used with equal success both on large construction sites, and in the construction of summer cottages and cottages.

Cement and wood are two fundamental materials that have been used in construction throughout human history. For a long time, these materials were used separately, and only in the early 20s of the last century, research began in the field of the physicochemical relationship between cement and wood. In the late 20s of the 20th century, cement was already widely mixed with wood chips, and in the early 1940s. people learned how to form slabs from a cement-bonded mixture. In 1940, the first fibreboards were produced, consisting of a pressed mixture of cement and long wood fibers. Subsequently, boards made of shorter fibers were produced, which became the prototypes of modern cement-bonded particle boards.

The slabs are made by pressing a molded technological mixture consisting of coniferous wood shavings, Portland cement, minerals and water.

O The main properties of cement particle boards are:

  • environmental and hygienic safety - do not contain formaldehyde resins, phenol, asbestos and other poisonous and harmful substances;
  • resistance to decay, are not affected by fungus and mold, resist the effects of termites, insects and rodents;
  • resistance to the effects of gasoline, oils, urea, solutions of acids and alkalis, solutions of disinfectants;
  • durability (warranty period of operation in building structures is at least 50 years);
  • high strength and wear resistance;
  • good soundproofing and thermal properties;
  • workability similar to wood with higher strength;
  • fire resistance and fire safety: combustibility group: G1 (low combustible), flammability group: B1 (hard to ignite), flame propagation group: RP1 (non-propagating), smoke-generating ability group: D1 (low-smoke-producing), combustion products toxicity group: T1 (low-hazardous);
  • resistance to atmospheric influences: DSP swelling in thickness in 24 hours no more than 2%, water absorption in 24 hours no more than 16%;
  • suitability for use both inside and outside residential and commercial premises;
  • variety of surface finishes: painting, plastering, cladding ceramic tiles, sheathing with wood, plastic, etc.;
  • suitability for use in all climatic regions.

The quality of the plate is ensured by strict quality control by a certified factory laboratory in accordance with GOST 26816-86 and the European standard EN 634.
