Specialized AAC Aluminum powder for Construction

What are the criteria for judging the quality of aerated aluminum paste?   The first indicator of the properties of aerated aluminum paste is the gas emission of aluminum powder. However, the production process of aerated concrete is much more complicated than that of ordinary concrete. A large amount of gas emission does not necessarily form ideal pores. If the gas emission is too fast or too early, hydrogen will easily escape from the slurry, causing collapse or pores to gather to form large pores. If the aluminum powder is gassed too late or the gas emission lasts too long (long tail), it is obvious that when the slurry gradually thickens and loses fluidity, the gas will be forced inside the slurry to form a connection between pores and gas guides. We call this phenomenon "holding air", which is quite harmful to the product. Therefore, when evaluating the properties of aluminum powder, its gas emission characteristics must also be considered.1.
