Advantages of aerated concrete construction
The development of construction technologies does not stand still, new and traditional materials are constantly appearing on the market and improving. One of these products is aerated concrete. This is a type of cellular concrete obtained as a result of solidification of a foamed mixture consisting of the following components: cement, gypsum, quicklime, quartz sand and aluminum powder. Such a material has many advantages:
- Excellent thermal insulation. Due to its cellular structure, aerated concrete prevents heat exchange and is comparable in its performance to wood.
- The possibility to abandon the usual cement mixture in favor of special adhesives. This approach in construction prevents the formation of so-called cold bridges.
- Good level of vapor and air permeability. This feature of the material creates a favorable microclimate in the room — natural circulation of air and moisture, again, comparable to wood.
- High accuracy when laying. Aerated concrete is the leader among similar building materials with respect to the error in the size of blocks, which allows you to build walls with minimal level differences. In addition, the size of the blocks and the laying technology increase the speed of construction.
- Aerated concrete is resistant to fire and other aggressive influences. In addition, due to the porous structure, it prevents the spread of high temperatures, and hence fire in adjacent rooms.
- It has a low weight with sufficient strength. This characteristic significantly reduces the overall load on the foundation of the building.
- Simple processing of blocks. Aerated concrete is easy to cut in the conditions of a construction site. This affects both the accuracy and the speed of the construction of walls and partitions.
- High frost resistance. High-quality aerated concrete is able to withstand up to 50 cycles of freezing-thawing, which is a fairly high indicator.
- Resistance to biological factors. Aerated concrete is not subject to destructive influence from rodents, insects or bacteria.
- Environmental friendliness. The material does not have any negative impact on people, animals and plants.
There are two types of aerated concrete according to the production method: hydrotational and autoclave. The difference lies in the method of drying the material. With the autoclave method, drying occurs at high temperatures, pressure and humidity. This approach promotes the formation of low-base calcium hydrosilicates, similar to natural minerals with high strength and stable structure. It is such aerated concrete that we use in the construction of residential complexes today.
