High-strength coal ash waste glass aerated concrete block and processing method thereof

Abstract

The invention discloses a high-strength coal ash waste glass aerated concrete block and a processing method thereof. The high-strength coal ash waste glass aerated concrete block is prepared from, by weight, 20-30 parts of coal ash, 30-40 parts of waste glass, 2-4 parts of gypsum, 3-5 parts of quick lime, 2-4 parts of kaolin, 2-4 parts of zeolite, 4-6 parts of cement, 1-2 parts of hydroxypropyl methyl cellulose, 1-2 parts of shell activated carbon, a proper amount of water, 0.2-0.4 part of tri-n-octylamine, 1-2 parts of additives, 1-2 parts of aluminum powder, 0.2-0.4 part of oxidized starch, 0.01-0.02 part of polyoxyethylene alcohol ether, 0.2-0.3 part of triterpenoid saponins, 0.01-0.03 part of sodium stearate, and 0.02-0.04 part of benzotriazole. The high-strength coal ash waste glass aerated concrete block is small in drying shrinkage value, good in anti-cracking ability and water resistance, various performances can meet the national standard, and compared with existing products, the strength of the high-strength coal ash waste glass aerated concrete block is obviously improved.

Description

technical field [0001] The invention relates to the field of new building materials, in particular to a high-strength fly ash waste glass aerated concrete block and a processing method thereof. 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. The production principle of aerated concrete blocks is to use siliceous materials, calcareous materials, in addition, add an appropriate amount of regulating materials and a small amount of gas-generating materials to add gas-generating agents (aluminum powder), through batching, stirring, pouring, pre-curing, Lightweight porous silicate products made by cutting, autoclaving, curing and other processes. Because it contains a large number of uniform and fine pores after being aerated, it is named aerated concrete. The pores in the air-entrained concrete b...

AI Technical Summary

Problems solved by technology

[0003] At present, there is a difficult technical problem in the production of aerated concrete blocks. The collapse rate of aerated concrete blocks is relatively high, resulting in a qualified rate of about 80%. The main reason for insufficient strength is that the existing gas-generating agent has poor gas-generating effect, uneven gas-generating, irregular shape, uneven size and uneven distribution of pores.
