Aerated concrete blocks is a modern wall material
Aerated concrete blocks – a modern material, which every day is gaining popularity among builders. This is not surprising, this material is much lighter than bricks, easier to install, the cost per square meter of the wall less, but, like other building materials has disadvantages.
At first glance, the creation of concrete blocks – an easy task, but it is not. Creating high quality material that meets all the stated criteria is possible only through the use of high-tech equipment.
The main components of concrete are:
- quartz sand;
The best quality and most expensive variety is the autoclave production method. The raw materials placed in an environment with high pressure, the components react and forms a porous structure. First, the output is large, the layers that are cut into blocks and sent for drying.
The main characteristics of the material
The strength of the material, the maximum among the counterparts. Depending on the brand, this characteristic varies from 1.5 to 2.5 kgf/cm2.
Ease of installation due to low weight, which allows without any difficulties transporting large volumes and separate blocks. Aerated concrete is easy to cut, even without the use of power tools, that allows to provide a block of any shape. Some brands have high levels of insulation, higher than the same of brick or cinder block Wall of concrete blocks gives very little heat in the cold time of year, and under the influence of the summer heat not heats the interior of the building.
Fire resistance one of the main characteristics of the material under the influence of gas burners aerated concrete does not burn and is not destroyed. Buildings constructed from this material relates to the high degree of fire safety.
The level of eco-friendliness this material is not inferior to natural and meets all required standards.
Biological effects are minimized. On the surface and in the concrete does not develop fungus, mold or bacteria, even under the most favorable conditions.
Disadvantages of concrete blocks
Aerated concrete blocks – brittle material that can be damaged during transport and after installation of the wall. This can be avoided if the building will have a solid Foundation, does not shrink. Also recommended the use of additional reinforced mesh, every 2-3 rows of blocks.
The structure of the blocks is such that the material absorbs moisture, which damages the finish. Very often there is a resolution layer of plaster applied to saturated with moisture blocks.
On the wall of aerated concrete blocks is problematic hang massive objects. This requires the use of special fasteners, which are not very effective or use normal screws, but they can paravati and spoiled.
A significant drawback of the material is low frost resistance, to obtain a material with high hardiness need to purchase a brand with high density.
The durability of the material in question, as it was constructed from this material at home, have not reached the manufacturer’s limits.
The advantages of concrete blocks before concrete.
Aerated concrete and foam concrete blocks similar in many ways, even look. But these materials have significant differences that separate applications of these materials. Why is the construction of aerated concrete block aerated concrete is better?
- Aerated concrete has the best vlagopoglotiteli.
- Due to the greater strength of aerated concrete it is possible to erect supporting structures.
- Rough surface holds the plaster.
- More durable during the installation of the fasteners into the wall.
