Autoclaved aerated concrete block and production process thereof

The invention relates to the technical field of concrete blocks, in particular to an autoclaved aerated concrete block and a production process thereof. The autoclaved aerated concrete block is prepared from the following components: cement, quick lime, gypsum, waste slurry, coal ash, coal ash slurry, aluminum powder paste and water. The production process comprises storage and treatment of raw materials, mixing, stirring, pouring, mixing, stirring, pouring, side plate returning and module oiling. According to the autoclaved aerated concrete block disclosed by the invention, the materials arewide in source and low in cost, and particularly, building garbage can be used, so that the concrete block is energy-saving and environmentally friendly; the block is high in intensity, high in toughness and convenient to construct; by adjustment of material proportioning, blocks meeting various absolute dry tolerance requirements can be prepared; a preparation process system is complete and suitable for popularization. 本
