Description

A kind of non-sintered brick and preparation method thereof containing engineering dregs
Technical field
The invention belongs to recovery and reuse of waste fields, and in particular to a kind of non-sintered brick and its system containing engineering dregs Make method.
Background technique
With the fast development of Chinese national economy, development of real estate is rapid, and the quickening of engineering construction paces leads to city The yield of city's building waste and engineering dregs is huge, these architecture sediments and come and be mainly derived from construction building site generation The earthwork, waste residue, mud.
The yield of China's engineering dregs is huge, and city is surrounded by dregs substantially.Architecture sediment occupies a large amount of soils, Polluted Soil Earth and underground water source influence many social concerns such as appearance of the city, have become building waste administrative department and the Environmental Protection Department shop front The important topic faced.In addition, relationship and the dregs consumption due to road distance need to pay the expense of statutory regulation, with The phenomenon that meaning is toppled over is with regard to this generation.Arbitrarily by building waste and engineering dregs be poured over public places such as road, greenery patches etc. without The place for approving disposition architecture sediment after examination, directly results in urban dust and flies upward, cause the deterioration of environmental quality.
Currently, for engineering dregs conventional process mode mainly by the way of simply filling, it is past in treatment process It is occupied toward will lead to a large amount of places, meanwhile, the placement of long-time weight easily causes surface collapse, and engineering dregs arbitrarily stack, The phenomenon that landfill, occurs gradually over the regions such as suburb, both sides of the road or even river, lake, causes serious dirt to urban environment Dye, also brings visual pollution, has evolved into city " scar ", and can this make these architecture sediments properly dispose to have become and work as The critical issue that must be taken into consideration during preceding Ecological Civilization Construction.
It is one of the method for realization engineering dregs resource utilization using engineering dregs brickmaking, but certainly due to engineering dregs Nature difference of body etc. can seriously affect the quality of brick obtained, and it is original that current brick-making method directly uses engineering dregs mostly Material keeps finished bricks obtained of poor quality, easy fracture without processing.
