When erecting buildings, the question almost always arises of choosing building materials. In this article, we will consider two types of materials for building walls: foam blocks and gas blocks, and try to find out what to build a house from and what is better - a foam block or a gas block.
The technology of production of gas blocks and foam blocks
These are two types of building materials that are made from different components and in different ways.
Foam blocks
Foam blocks are made of foam concrete - a porous material consisting of cement, sand, water and foam. Sometimes they can add some other components, such as ash. The foam concrete acquires a porous structure , thanks to special chemicals that are part of the solution. This foamy solution is poured into special forms and, after solidification, finished products, including foam blocks, are obtained. Due to the porous structure, foam blocks have lightness, low thermal conductivity and good sound insulation. This building material is very durable and durable.
Gas blocks
Now, to answer the question of which is better - a foam block or a gas block, we consider
properties of
aerated concrete. Gas blocks also have a porous structure and the same properties that are inherent in foam blocks, but they are made using a different technology. The composition of aerated concrete includes cement, lime, sand, aluminum powder and water. Pores appear when aluminum powder reacts with cement. The finished mixture is mixed and held for a certain time until it gets the right condition. Then the resulting array is cut into blocks using special strings. Then they are placed in an autoclave, where all excess water evaporates from them, they acquire their final form and properties, and become ready for consumption. They are lightweight and have good soundproofing characteristics, as well as foam blocks. Gas blocks have high strength and low thermal conductivity. These indicators are slightly higher than that of foam concrete, but still it is not easy to determine which is better - a foam block or gas block, due to the many advantages of foam concrete.
Differences between foam blocks and gas blocks
In search of an answer to the question of which is better - a foam concrete block or a gas block, it must be said that these materials have only one difference - the high hygroscopicity of aerated concrete. Foam concrete, on the contrary, has low hygroscopicity.
What is better to build
Both materials have many similar advantages. So what is better to build a house from? The foam block for this is as good as the gas block. Both materials make excellent one-story and two-story houses. They have heat conductivity indicators that compete with wood and are in many ways superior to ceramic bricks. Since they contain no harmful substances, they are environmentally friendly to humans. But gas blocks have one drawback, because of which it is inferior to foam blocks in terms of efficiency - this is the complexity of the technology of erecting walls from this material, due to its hygroscopicity. Gas blocks are delivered from the factory with a high level of humidity, so after the construction of the house you can not immediately carry out exterior decoration. It is necessary to wait several seasons until the walls completely dry or equip a ventilated facade, and this leads to an increase in construction costs. So, determining what is better - a gas block or a foam block, the scales leaned toward the latter because of its efficiency.
