Red mud autoclaved aerated concrete building block and preparation method of red mud autoclaved aerated concrete building block
The invention discloses a red mud autoclaved aerated concrete building block and a preparation method of the red mud autoclaved aerated concrete building block. The building block is prepared from the following ingredients in parts by weight: 5 to 15 parts of red mud, 15 to 60 parts of pulverized fuel ash, 2 to 8 parts of plaster, 10 to 35 parts of quicklime, 5 to 10 parts of concrete, 0.01 to 0.03 parts of aluminum powder and water. The red mud is used for replacing phosphorus slag and undergoes a series of reactions with raw materials such as the pulverized fuel ash, the plaster, the quicklime, the concrete and the aluminum powder to prepare the aerated concrete building block; the product weight is light; the strength is high; the stability is good; the heat conductivity coefficient is low; the performance is excellent; the problem that the red mud cannot be easily and synthetically utilized is solved; the stored red mud can be fast digested; the goal of saving national resources is achieved, a lot of soil is also restored; in addition, the production process is environment-friendly and has no pollution; a new path is opened up for the comprehensive utilization of the red mud.
