Abstract

The invention discloses a novel lightweight aerated concrete block. The novel lightweight aerated concrete block is prepared from the following components in parts by weight: 250-350 parts of water, 3-8 parts of aluminum powder, 60-80 parts of gypsum, 80-90 parts of lime, 150-200 parts of tailings, 150-200 parts of silt, 30-50 parts of slag, 10-20 parts of talc powder, 60-80 parts of fly ash, 70-90 parts of cement, 3-8 parts of an additive, 30-50 parts of a foam stabilizer and 5-20 parts of soda ash, wherein the silica content of the tailings is 90wt% or higher, the silica content of the silt is 80wt% or higher, and the silica content of the slag is 80wt% or higher. A plurality of through holes penetrating two length ends are formed in the aerated concrete block at intervals in the length direction and are filled with thermal insulation cotton.

Description

technical field [0001] The invention relates to a novel lightweight 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 object of the present invention is to provide a novel lightweight aerated concrete block with superior physical properties. [0004] The technical problem solved by the p...
