Construction waste recycling method

Abstract

The invention relates to the technical field of construction waste treatment, in particular to a construction waste recycling method which comprises the following steps of: S1, performing classifyingand recycling, namely, performing classifying according to material types obtained by splitting on a construction site, and obtaining waste steel bars and concrete blocks; S2, performing high-temperature smelting on the waste steel bars, and performing cooling to form a brick framework; S3, crushing selected concrete blocks to form recycled aggregate; S4, doping the recycled aggregate into cementmortar to form aggregate slurry; and S5, placing the brick framework in a brick mold, pouring the aggregate slurry, and forming a recycled brick through solidification. With the method adopted, construction waste can be reasonably utilized, and the recycled brick can be produced. The recycled brick has the advantages of light weight, firm structure and better sound insulation and thermal insulation properties.

Description

technical field [0001] The invention relates to the technical field of construction waste treatment, in particular to a construction waste reuse method. Background technique [0002] At present, it is solid waste generated during the construction, renovation, expansion or demolition of buildings. According to the different sources of construction waste, it can be divided into construction waste and demolition construction waste. Construction waste, as the name implies, is the solid waste generated in new construction, renovation or expansion projects, and demolition construction waste is the construction waste generated during the demolition of buildings. [0003] Construction waste has a wide range of erosive effects on our living environment. If construction waste is ignored for a long time, it will have a bad impact on urban environmental sanitation, living conditions, and land quality assessment. First of all, after a large amount of land is piled with construction was...

Problems solved by technology

[0005] The above-mentioned existing technical solutions have the following defects: in the process of crushing construction waste, the construction waste falls into the crusher from the discharge end of the first conveyor belt for crushing, and the broken pieces enter the drum screening machine, which is harmful to the construction waste. The waste is graded, and the large pieces of waste that do not meet the requirements fall on the waste conveyor belt, and then they are sent to the crusher for crushing treatment in the later stage, which can only play the role of crushing and classifying construction waste, and the obtained is recycled aggregate.
