Gray aerated concrete blocks are high-performance homogeneous porous silicate products made of cement, sand/fly ash, lime as the main raw materials, aluminum powder (paste) as the foaming agent, and cured under high temperature and high pressure. It has excellent properties such as light weight, thermal insulation, fire resistance, impermeability, and environmental protection, and can be used for filling walls and outer walls of buildings.

Autoclaved sand aerated concrete blocks can be sawed and planed, and are easy to process. Its construction efficiency is 4 to 5 times that of traditional red bricks. Combined with ultra-thin ALC nano insulation board, it effectively solves the problem of cold and hot bridge treatment on beam and column surfaces, and exerts its self-insulation function, making it a good insulation material.
