Description

A kind of regeneration aggregate aerated bricks and preparation method thereof

Technical field

The present invention relates to aerated bricks technical field, be specifically related to a kind of regeneration aggregate aerated bricks and preparation method thereof.

Background technology

In recent years, along with the quickening of process of industrialization and the raising of the level of urbanization, also various environmental stresss and problem have been brought, the various solid wastes that Industrial processes produce and urban construction are removed and are remake the solid waste brought etc. and perplexing always resident's living environment, the present invention adds in aerated bricks solid waste as starting material, realize the cyclic utilization of waste, reduced the pollution to environment, met strategy of sustainable development requirement.

Aerated bricks is the air-entrained concrete building block of producing by autoclave at high temperature apparatus and process.Air-entrained concrete building block is take cement, slag, sand, lime etc. as main raw material, add foaming agent, the solid block forming through stirring moulding, steam press maintenance, gas concrete is by purposes, can be divided into five kinds, non-bearing building block, bearing building block, insulation block, wallboard and roof boarding.

Tradition solid clay brick weight is large, not only wastes outside national clay resource, price height, and cannot meet the requirement of some special buildings brick, and therefore common brick use has been completely forbidden in present many advanced areas, replaces and advocates energetically aerated bricks.Compare with normal concrete brick with traditional clay brick, aerated bricks is not only lightweight, also has heat insulating, an advantage such as sound-proofing properties is excellent, shock resistance is strong, good processability, resistance to elevated temperatures are good, strong adaptability.But China, about the production technology of aerated bricks is ripe not enough, makes aerated bricks Development Technology slow at present, also cannot meet the demand of multiple market.
