It is worth noting that foam concrete is different from aerated concrete. Its manufacture is carried out using another technology. The building material includes sand, cement, water and foaming agents. When stirring these components, a ready -made mixture forms mechanically, which acquires a cellular structure when solidifying. Closed pores are responsible for lightweight, excellent sound insulation and thermal insulation, but do not allow to penetrate moisture or dust inside the finished block, maintaining its monolithic and the strength of the wall. The pores are always open, so the scope of its use is limited.
