Abstract

The invention discloses an aerated concrete block and a preparation method thereof. The aerated concrete block is prepared from raw materials in parts by mass as follows: 20-30 parts of slag, 30-35 parts of tailings, 20-30 parts of phosphogypsum, 10-20 parts of fly ash, 1-2 parts of graphite, 1-3 parts of concentrated high foamer, 0.5-1 part of vermiculite and 7-10 parts of sodium silicate. The aerated concrete block can be produced in a factory in a large batch manner with the traditional aerated concrete block production process, the strength of the aerated concrete block also meets certainstandard, by means of industrial waste residues discharged by a chemical enterprise, industrial refuse produced by the chemical enterprise is used to the greatest extent, use rate of lime and cement is reduced, brick manufacture cost is reduced greatly, and foaming capacity can be controlled effectively by changing various parameters of the production process.

Description

technical field [0001] The invention relates to the technical field of aerated concrete blocks, in particular to an aerated concrete block and a manufacturing method thereof. Background technique [0002] Air-entrained concrete block is a kind of building material that fully foams the foaming agent by mechanical means, mixes the foam and cement slurry evenly, and uses the pumping system of the foaming machine for cast-in-place construction or mold molding. It has become a new type of lightweight insulation material with a large number of closed pores, and the aerated concrete block has certain sound insulation, light shock resistance and compression resistance, because these reasons are widely used in the production of buildings today. [0003] The disadvantages of the above-mentioned traditional aerated concrete blocks are: the addition of fly ash is low, and the prices of lime and cement are high, resulting in high brick costs, and the foaming efficiency cannot be well con...
