Autoclaved aerated lime brick and preparation method thereof
The invention relates to an autoclaved aerated lime brick. Calculated in percentage by weight, the raw material formula of the autoclaved aerated lime brick comprises, 70-90% of fly ash, 0.5-5% of cement, 5-15% of lime, 1-10% of gypsum, and 0.01-0.2% of aluminium powder. By improving the formula and optimizing concrete technological parameters in the preparation method, fatty acid soap and gleditsia sinensis powder are not needed, also the usage amount of cement and aluminium powder is further reduced, environmental pollution is reduced, and the raw material cost is reduced. Additionally, fly ash and gypsum do not need mixed grinding, the preparation step is reduced, and the production cost is further reduced. Additionally, the performance indexes of the prepared autoclaved aerated lime brick are all qualified.
