Autoclaved aerated sand brick and preparation method thereof
The invention relates to an autoclaved aerated sand brick and a preparation method thereof. The autoclaved aerated sand brick is prepared from, by weight, 70-90% of sand, 1-10% of cement, 5-15% of lime, 1-10% of gypsum and 0.01-0.2% of aluminum powder. By improving the formula and optimizing specific technological parameters in the preparation method, sand and gypsum do not need to be subjected to mixed grinding, preparation steps are reduced, and produced finished products are reduced; besides, performance indexes of the autoclaved aerated sand brick prepared through the method are all qualified.
