Abstract

The invention discloses a production method of improved aerated concrete building blocks. The method comprises the following steps: 1) preparing materials; 2) performing mixing and stirring; 3) after pouring, performing aerating and primary solidification in a primary maintenance room at the temperature of 45-60 DEG C with the primary maintenance time being 2 h, and performing cutting after primary maintenance; 4) performing maintenance stage by stage; and 5) carrying out processing to obtain final building blocks, after the building blocks are taken out, inspecting the building blocks, and performing classified stacking. The aerated concrete building blocks comprise, by weight part, 250-350 parts of water, 3-8 parts of aluminium powder, 60-80 parts of gypsum, 80-90 parts of lime, 150-200 parts of tailings, 150-200 parts of silt, 60-80 parts of coal ash, 70-90 parts of cement, 3-8 parts of an additive, and 5-20 parts of soda ash, wherein the silica content of tailings is more than 90 wt%, and the silica content of slit is more than 80 wt%.

Description

technical field [0001] The invention relates to a production method of an improved 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 different, and the production processes are also different, resulting in a gap in performance. Contents of the invention [0003] The object of the present invention is to provide a production method of an improved aerated concrete block with superior phy...
