Scope of aerated concrete blocks
This material is used in completely different areas of construction. First, it is well suited for for single-layer walls of .The thickness of aerocrete blocks for these purposes is 30-48 cm. Secondly, it is also used and for the erection of external two-, three-layer walls .The width of the blocks should be 20-36.5 cm. Thirdly, this material is used to create fences and partitions .
The fact is that it is much lighter than a typical brick( which is important when creating such designs).The weight of the gas block is only 19.9 - 25 kg. Fourthly, this material is used as the chute blocks for further reinforcement or filling with concrete( including for the foundation).That is, they fulfill the task of formwork. That is why the walls with such blocks become more homogeneous, which makes the plastering process easy and simple.
Aerated concrete blocks disadvantages and advantages
If we talk about gas blocks, the characteristics of which can have both its pluses and minuses, then the advantages in this material are much greater than the disadvantages. However, the latter are also available. So, what are its properties?
- Heat and sound insulation of the is ensured by a special material structure. Compared with a brick, aerated concrete is 2 times more damped by sound and 3 times more retains heat. Plus, everything is provided with a favorable microclimate and heat is maintained even in the most severe frosts.
- Resistance to the biological environment of ( fungi, bacteria, molds).Even at a temperature of 30 ° C and an air humidity of 98%, no microbes appear. This is its significant advantage over the tree, since the material does not need to be treated with antiseptics.
- Easy and simple to lay .The weight of the block averages 20-25 kg., And its size replaces the masonry of 28 bricks. This greatly simplifies the installation and allows you to save on the solution in 5-7 times.
- Fire, water and frost resistance .According to international standards, this material withstands more than 200 cycles of freezing-defrosting, has the highest degree of fire safety, and is waterproof( its moisture index is always kept at 5%).
- Easy processing .This material is easy to saw, cut, make holes in it. At the same time, it does not crumble in the process of work and precise geometric dimensions are achieved. This allows you to create almost any design projects.
However, in addition to the advantages in this material, there are a number of shortcomings. Firstly, this is a relatively low bending strength( as a rule, in blocks with a low thermal conductivity index).Secondly, brittleness at low density. However, if you approach the process of choosing aerated concrete competently and choose a product about these or other parameters( there are several types), then it is possible to select quite worthy material for your house.
Aerated concrete blocks technical specifications
Each building material is equipped with its own characteristics. They have gas-concrete blocks: dimensions, weight, density, compressive strength and others. If we talk about how it has dimensions, its length is always 600 mm, height 250 mm, and the width can be different from 75 to 500 mm. Weight directly depends on the size and volume of the gas block. On average, from 4.5 to 45 kg.
Compressive strength directly depends on the brand( 300-600) and varies between 1.5-3.5 kgf / cm2.That is, the higher the mark, the greater the strength it has. Frost resistance is approximately the same everywhere 35-50 cycles. The lowest vapor permeability of the D600 material and it is 0.16 mg / mchPa, the highest at D300 and is 0.26 mg / mchPa. In general, aerated concrete blocks, the characteristics of which have just been listed, have some other properties( volume, number of pieces in the pallet), but they are most often spoken by sales consultants themselves.
Aerated concrete blocks, videos with varieties of which are presented on our website, will be an excellent material for the construction of houses. However, it is worth taking into account the fact that if you are building with your own hands, then when building load-bearing walls from this material, the maximum height of the building can be 3 floors.
