Problems solved by technology

[0002] As a new type of wall material, air-entrained concrete is a low-energy, environmentally-friendly new building material, which belongs to the building materials promoted by the state. However, because ordinary air-entrained concrete is made of cement, fly ash, quicklime, gypsum, etc. Large shrinkage value, low strength, water seepage, non-corrosion resistance, poor heat insulation, single source of material, etc. Therefore, further research on aerated concrete block technology is urgently needed to further meet market requirements

Abstract

Provided is an aerated concrete block with composition of mica powder and fly ash and a preparation method. The aerated concrete block is characterized by being prepared from, by weight, 12-15 parts of cement, 15-20 parts of quicklime, 12-16 parts of gypsum, 30-35 parts of fly ash, 0.2-0.4 parts of aluminium powder, 30-35 parts of mica powder, 12-16 parts of talcum powder, 2-3 parts of ferric nitrate, 2-3 parts of lard, 2-3 parts of sodium dodecyl benzene sulfonate, 1-2 parts of iron mine tailings, 2-3 parts of sodium persulfate, 3-4 parts of oil foot, 3-4 parts of polyisobutylene and 8-10 parts of alum. The aerated concrete block employs composition of mica powder and fly ash, and is advantaged by high temperature resistance acid and alkali resistance, corrosion resistance and high block strength.

Description

technical field [0001] The invention belongs to a building material technology, in particular to a concrete block and a preparation method thereof. Background technique [0002] As a new type of wall material, air-entrained concrete is a low-energy, environmentally-friendly new building material, which belongs to the building materials promoted by the state. However, because ordinary air-entrained concrete is made of cement, fly ash, quicklime, gypsum, etc. Large shrinkage value, low strength, water seepage, no corrosion resistance, poor heat insulation, single source of material, etc. Therefore, further research on aerated concrete block technology is urgently needed to further meet market requirements. Contents of the invention [0003] The purpose of the present invention is to provide mica powder and fly ash composite aerated concrete block and its preparation method, so that the block has high temperature resistance, acid and alkali resistance, and corrosion resistanc...
