The core function of aluminum powder in autoclaved aerated concrete is to act as an air entraining agent, which reacts chemically with alkaline substances such as calcium hydroxide in the slurry to produce hydrogen gas, forming a large number of small and uniform pores, enabling the concrete to achieve the core characteristics of lightweight and thermal insulation.
At the same time, by controlling the air entraining speed and volume, the dimensional stability of the body expansion molding is guaranteed.
