Abstract

The invention discloses a method for producing a multi-functional aerated concrete block. The method comprises 1) preparing 250 to 350 parts by weight of water, 3 to 8 parts by weight of aluminum powder, 60 to 80 parts by weight of gypsum, 80 to 90 parts by weight of lime, 150 to 200 parts by weight of tailings, 150 to 200 parts by weight of silt, 30 to 50 parts by weight of slag, 60 to 80 parts by weight of fly ash, 70 to 90 parts by weight of cement, 3 to 8 parts by weight of additives, 30 to 50 parts by weight of a foam stabilizer and 5 to 20 parts by weight of sodium carbonate, 2) carrying out mixing stirring, 3) carrying out pouring, then carrying out gas formation initial coagulation at 45-60 DEG C through an initial curing chamber, carrying out initial curing for 2h and then carrying out cutting, 4) carrying out segmented maintenance, and 5) processing a finished product, discharging the finished product out of a reactor, carrying out inspection and carrying out classification stacking.

Description

technical field [0001] The invention relates to a production method of 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 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 a multifunctional aerated concrete block with ...
