Houses made of gas silicate blocks - advantages and disadvantages
Construction of houses from gas silicate blocks has long been popular in our country and has a number of advantages:
- houses have excellent sound and heat insulation, have a high frost resistance index;
- cellular structure gives the walls lightness and allows them to "breathe";
- block has high strength and low density, which makes the construction more light, and the load on the foundation is reduced;
- material is absolutely resistant to all atmospheric influences;
- gas silicate provides buildings with high fire safety and fire resistance.
There are not many drawbacks to this building material - it's low strength to bending and compression, as a result of which walls of gas silicate blocks can be deformed.
Laying of walls from gas silicate blocks - preparation of material and tool
Laying of gas silicate blocks is carried out on a special glue or cement-sand mortar( in the ratio 1: 3) and always begins with corner blocks, which should be carefully leveled. With a competent approach, the house will be built quickly, but this will not affect its longevity at all.
For the preparation of mortar and laying blocks you need the following tools: trowels, rubber hammer, grater, saw, grooving tool, plane, level, square for marking, soft brush, drills, hand drill with nozzle and container for solution.
Construction of gas silicate blocks is widely used for the construction of houses, country cottages and cottages, and is available to people with any financial wealth. And many do not miss the opportunity to make these blocks with their own hands directly on the construction site.
Construction of gas silicate blocks - stages of operation
Laying of gas silicate blocks occurs in several stages. First of all, it is necessary to conduct waterproofing, it prevents penetration of moisture. For this, the foundation is laid with a roofing material, planted on a cement-sand mortar.
Next, put the first row, serving as a kind of support for the wall, and therefore it must be treated with particular attention. It usually starts from a higher angle of the house. It is laid on the solution, by which all the unevenness of the foundation is compensated.
Blocks are carefully leveled using a hammer and a level: the evener the row, the easier it will be to make the subsequent masonry. All irregularities on the laid out surface are immediately removed using a float and a plane, and the remaining garbage is swept off with a soft brush.
Laying of the following rows can continue with the use of adhesive composition, which should be applied to the horizontal surface and from the sides of the block. The second and subsequent series also begin with a corner, but spread out already in the opposite direction. This alternation makes the construction more durable. Put the blocks of gas silicate with their own hands will not be difficult, because they are very light and easy to use.
Finishing of gas silicate blocks, its durability and appearance largely depend on the correct selection of finishing materials, the order of work and the general construction of the building. There are a lot of options for finishing the gas-silicate surface, but the most common ones are vinyl siding, decorative brickwork, various hinged panels and, of course, plaster.
Plaster of gas silicate blocks from all types of finishing takes first place. It should have a number of protective properties, such as frost resistance, weather resistance, low water absorption, resistance to cracks and compression.
