Cement strand board: characteristics and application

Cement-bonded chipboard (DSP) is a material that is actively used in construction and repair work. Such plates are in demand in a huge number of spheres. But even these fundamental constructions are represented in a wide variety in the construction market. Before you opt for a specific product, you need to familiarize yourself in advance with the features of these structures and the areas of their use.

Cement strand board is manufactured using special technologies. The process of creating a DSP includes the following steps:

• The solution is based on water, which is poured into a special mixing tank. Aluminum, salts and liquid glass are also added to the container;
• to achieve mineralization, chips are added to the mixture;
• the next step is the addition of cement;
• to obtain a DSP block, the solution is poured into a special form;

• a certain thickness of the substance is given using a press;
• after pressing, the product undergoes heat treatment, the implementation of which takes into account the characteristics of the components of the raw material;
• in order for the substance to harden, it is placed in special chambers. There, at a temperature of 80 ° C, the components are fixed;
• after curing, the web is cut into sheets. Their sizes are determined by GOST.

Cement-bonded products have a number of fixed technical characteristics that explain many of its properties:

• the composition of a quarter is made of wood chips, a little more than 8% is water, the main component is Portland cement and the share of additional impurities accounts for 2 and a half percent;
• material thickness ranges from 8 to 12 mm;
• plate width is 120 or 125 cm;
• length - from 2.6 to 3.2 m. To order, you can choose a model with a length of up to 3, 6 m;
• the weight of one square meter of DSP, having a thickness of 8 mm, reaches 10 kg.

The material has a high density, which reaches 1300 kg / m3. In the process of moisture absorption, the density can increase by 2 percent. The limit of the ability to absorb water usually does not exceed 16%.

Sheets have a fire resistance class of G1, meaning that the material has a low flammability. Thermal conductivity is 0, 26 watts.

All listed characteristics allow you to select the required number and parameters of building material.

There are also different types of materials for plates and cast products from DSP:

• Xylolite - high strength material with good thermal insulation. Such plates are often used for flooring. Products are presented in a wide range of colors.
• Fibrolite is a raw material consisting of long fibers. It has high thermal insulation properties and soft texture. Biological factors do not have a strong impact on this type of DSP.
• By small materials can be attributed arbolitwhich is used in various fields.

Like any building material, DSP has a number of advantages and disadvantages. The advantages of such plates include:

• The material is very resistant to moisture and temperature extremes. Plates withstand up to 50 frost cycles. This characteristic significantly affects the service life of the plates.
• The raw materials used to create such partitions are absolutely safe for human health. DSP does not emit harmful toxins and does not cause allergic reactions.
• Cement strand board is ideal for various transformations. With it you can use any methods of finishing and change the surface of the product at will.
• Wide range of. In modern building stores you can find a rich variety of products.
• Affordable price is an important advantage.Since the material is often used in building a house from scratch, purchasing a large number of material will not adversely affect your budget.

• Plates of this type are very durable.
• An important feature when using DSPs as interior partitions is their good sound absorption. They create the necessary level of sound insulation and additional comfort in the room.
• Unlike some other materials, DSPs are not exposed to parasites, harmful insects or rodents, which can periodically appear in a private home.
• The material is not subject to instantaneous fire. The stove can ignite only when exposed to an open flame.
• DSPs are very durable. Such plates can last more than a dozen years.

• Cement-chipboard products are easy to use. On such a surface it is convenient to carry out various repairs using a drill, punch or knife.
• The fixed size of products contributes to a significant ease of installation.
• The material is resistant to decay processes.
• When cement strand board is used for floor screeding,it contributes to significant savings, compared, for example, with self-leveling compounds or cement-sand leveling option.

The negative properties of DSPs include:

• Products can reach a large mass, which significantly complicates their use in high spaces. Large weight due to the high density of the material.
• The material is non-plastic. If you try to bend such a plate, you can break it. The risk of breakage during construction explains the need to purchase material with a margin.

Based on the data presented, it is clear that DSP has significantly more advantages than disadvantages. The disadvantages of such products are easily compensated by the advantages.

Cement-bonded chipboards are used in various construction and finishing areas. The most common uses are:

• Outdoor. It implies the suitability of plates for finishing the facade of residential premises, the use of plates as a basis for fencing. Work on the implementation of permanent formwork is also not excluded. Sheets of TsSP can be used both in private, and in the industrial sphere.From these plates both protective structures for beds in private houses and parts for industrial enterprises are constructed.

• Cement particle board is indispensable in the construction of a frame house. In this case, it acts as an excellent insulation. Products are used to create a warm floor. They are also often used for walls, subsequently creating an interesting decor on the plates.
• The resistance of the material to moisture can be used as a ceiling covering in saunas. and other types of premises where the humidity level is elevated.

• Often these sheets are used to create partitions in rooms. To serve as a separator plate served longer, it is envisaged to cover them with a special paint that performs a protective function.
• The best varieties of cement-bonded particle boards are used to create furniture.
• The material is used to create window sills. It becomes a more affordable alternative to wooden structures, and at the same time it serves for at least a long time.
• From dense slabs it is permissible to manufacture a special foundation for roofing in private houses.

• A very common area of ​​application of the plates is the restoration. The material is often used to give older buildings a better look. In addition, because of its relatively low price, the products are quite suitable for large-scale works.
• With the help of thin plates it is often carried out to finish such attributes of private houses as a fireplace and chimney.
• Cement-bonded chipboard is sometimes used as an alternative to cement when screeding floors.

DSP suitable for various kinds of work. The following options for processing cement-bonded products:

• cutting to the required size;
• making holes in the plates with a drill;
• milling work;
• increase the strength at the joints using face grinding;
• applying a primer, acrylic or silicone paints;
• lining ceramics;
• taping.

These features characterize the DSP material as an excellent base for any coverage and as a source for the realization of creative ideas.

There are a number of manufacturers DSP products that are very popular in the construction market and deserve positive feedbackbuyers.

Leningrad firm "TsSP-Svir" provides light gray products with a calibrated surface. Also among the range of the company there are polished models. The production is based on European standards and high-quality equipment from Germany.

Bashkir enterprise "ZSK" It is also distinguished by the production of high quality slabs in accordance with GOST. The main feature of the product is its increased resistance to temperature fluctuations and the influence of weather conditions.

Kostroma company "MTI" characterized by special geometric characteristics of products and clear adherence to all quality standards.

Tambov firm "Tamak" produces high quality slabs. The company very carefully approaches its business, so it is difficult to find even the slightest marriage among their products.

Omsk company "Stropan" engaged in the production of elastic cement particle boards of various thicknesses. The company is also distinguished by the creation of sheets with increased sound and heat insulation.

Depending on how you decided to use DSPs for your home, you should listen to various recommendations for the correct installation of these plates.

The most common option is to warm the walls or the floor with cement-bonded sheets. To implement this procedure, it is necessary to prepare in advance the surface of the walls, providing it with a crate of metal and wood. You must have special cells that have a fixed size of 500 * 500 mm.

During the installation process, leave a space of 1 cm between the plates. It is covered with a special overlay, in which quality you can use finished products from the same material or create them yourself from residual raw materials.

To insulate the frame construction of the slab, it is necessary to install both the outer and inner sides of the walls simultaneously. If you want to insulate the room of economic type, then it is permissible to leave a small space between the base of the wall and the sheet DSP.

In private homes, many lay cement-bonded chipboard on wooden floors to make them warmer. To correctly carry out this process, you must follow a special algorithm:

• In order to avoid creaking floors in the future, the base is adjusted and secured with self-tapping screws. When adjusting the base coat, be sure to remove the rotten boards and replace them with new ones. If the surface has cracks or cracks of an irrelevant nature, they must be treated with a putty.
• The rooms are measured taking into account the finding of the long side of the canvases across the boards.
• It is necessary to design a paper laying scheme for DSPs on paper.
• With the help of the grinder, you need to cut the sheets to the required parameters, if necessary.
• In the direction from the corner to the corner the plates are being assembled. In this case, it is best to fix the products using zinc screws.
• The seams between the sheets should be primed. Only after the completion of all stages can the exterior finish of the flooring be carried out.

A special process is the use of DSP for floor screed.In order to properly carry out the dry screed procedure, it is necessary to lay the sheets on a special aggregate with granules and metal profiles from drywall or wooden bars. Self-tapping screws for fixing cement-bonded particle boards should fit the cross-section of the beams and the material from which they are designed. This leveling method is used only if the difference in level differences is more than 6 cm, raising the level with the help of cloths is permissible on average to a height of 7 to 10 cm.

In order to avoid errors in the process of screed implementation using DSPs, it is important to follow the strategy of this work:

• it is necessary to carry out a breakdown of the finishing level on the walls of the room, that is, to determine the height of the new flooring;
• should be laid a couple of layers of plastic film, which is used as a material for insulation;
• damper tape should be attached to the surface of the walls located around the perimeter of the room;
• beams are installed in increments equal to the size of the rule, since it is unacceptable that the distance between them exceeds 0.5 m;

• after the beams are set out clearly in level, they should be fixed using dowels and screws;
• the space between the installed rails must be filled with bulk material, then it must be tamped;
• after laying the DSP and fixing them with screws to the beams at a distance of 10 to 15 cm.
• after cleaning the surface from dust and debris, you can lay the finishing floor covering.

To install cement-bonded chipboard ideally, you need to listen to a number of additional recommendations:

• In order to work with DSPs carefully, you should not do it alone. Remember that the larger the plate has, the greater the brittleness. Therefore, especially when installing large products, work must be done with an assistant.
• Do not stack products close to each other, otherwise in the future the surface will be damaged when the products swell due to humidity.
• To avoid cracking products, arrange the holes with fasteners not at the very edges of the plates, but departing from their borders by a couple of centimeters.
• If the fixation of cloths is not carried out on a wooden surface, but for example, on a metal profile, then only metal screws will be needed for fastening.
• In the process of sharp plates it is best to use a hacksaw blade. It will help to avoid strong dust formation and allow you to cut the product quite smoothly.

Cement-bonded web is a material that has proven itself in the Russian market for a long time. To use this raw material correctly, it is necessary to take into account all the recommendations of professionals. Using the versatility of the plates and tips on their installation, you can perfectly finish the whole house with this material and enjoy its quality for a long time.
