Autoclaved aerated concrete brick and preparation method thereof
The invention relates to an autoclaved aerated concrete brick. The autoclaved aerated concrete brick is prepared from, by weight, 60%-80% of coal ash and/or sand, 10%-20% of waste, 0.5%-10% of cement, 5%-15% of lime, 1%-10% of gypsum and 0.01%-0.2% of aluminum powder. By means of improving the formulation and optimizing specific process parameters in a preparation method, no fatting acid soap or gleditsia sinensis needs to be added; the use amount of the cement and the aluminum powder is further reduced, environmental pollution is reduced, and raw material cost is reduced. In addition, the coal ash and the gypsum do not need to be mixed and ground, preparation steps are reduced, and production cost is further reduced. The waste is used as part of the raw materials, the waste can be recycled, and raw material cost is reduced. In addition, all performance indexes of the prepared autoclaved aerated concrete brick are qualified.
