Gas silicate blocks
Silicate blocks are an indispensable find in the construction of houses and the erection of walls. Using their help, you can quickly and inexpensively build a house yourself, knowing some of the subtleties regarding this material and possessing at least some building skills.
Technical characteristics of gas silicate blocks
Blocks have a cellular structure. The composition includes cement, water, fine sand, lime, gypsum, as well as aluminum powder, which acts as a blowing agent. Such a porous structure gives the material good heat and sound conductivity.
Gas silicate block is a non-combustible material, with increasing temperature up to 500 degrees, its strength only increases.
The material has excellent thermal insulation. According to experts, the wall of gas silicate blocks with a thickness of 300 mm corresponds to the thermal characteristics of the walls of their bricks with a thickness of 900 mm.
Compared to ordinary brick, gas silicate blocks have a rather low strength, due to the presence of pores in the structure. Therefore, this material is used in the construction of buildings no higher than 3 floors
Density Table:
- 350 kg / m³ are used only as a heater;
- 400 kg / m³ are used for the construction of partitions, not used as load-bearing walls;
- 500 kg / m³ are suitable for the construction of cottages and low-rise buildings;
- 600 kg / m³ is used for taller buildings.
The silicate block is lightweight and strong enough, hard material. It has a large size, which allows to accelerate construction work on the construction of houses and structures, and also has good heat and sound insulation. Blocks are easy to saw or vice versa to connect if necessary, which often happens if you need to change the design of the room. It contains only environmentally friendly materials. At high temperatures, the material does not emit toxic substances. Due to the porous structure, gas silicate blocks have the property of regulating the microclimate in the house (they absorb excess moisture and, if necessary, give it away). But it is worth noting that the material it has the property of getting wet, so the walls of the erected house must be sheathed immediately, preventing them from standing in the cold or in rain. The structure of gas silicate blocks is porous and if it is often wetted, it is possible to form a fungus, which is then very difficult to get rid of.
Styling tips
The construction and erection of houses should be carried out only on a monolithic strip foundation, otherwise there will be a crack formation. Before you start laying out the first layer of gas silicate blocks, it is necessary to put waterproofing. You can use roofing material for this, which must be fixed with a solution of sand and cement. In order for the adhesion between the blocks to be better, they are primed by spraying each step row.
- Expose corner blocks, align them and impose the following, constantly monitoring the evenness of the walls. You can use any construction level for this.
- Remove all irregularities on the surface.
- Stacked from the corner, in a checkerboard pattern, every three or four rows, to improve the ligament, lay construction gratings.
There is nothing special in laying, all rows are laid equally. Observing technology. When carrying out such construction works with the help of a level, you can help yourself pull a thread and keep the level of its horizon so that gas silicate blocks do not accidentally shift to one or the other side.
