Description

technical field [0001] The invention relates to a multifunctional aerated concrete block. Background technique [0002] Air-entrained concrete block is a new type of building material that is lightweight, porous, thermal insulation, good fire resistance, nailable, sawable, planable, and has certain earthquake resistance. As early as the early 1930s, China began to produce this product and it was widely used. For example: Shanghai International Hotel, Shanghai Building, Fuzhou Building, People's Bank of China Building and other high-rise buildings. It is an excellent new building material and has the advantages of environmental protection. However, the formulations of various aerated concrete blocks are not the same at present, resulting in a gap in performance. Contents of the invention [0003] The purpose of the present invention is to provide a multifunctional aerated concrete block with superior physical properties. [0004] The technical problem solved by the pres...
