Construction waste recycling and reusing process

Abstract

The invention discloses a construction waste recycling and reusing process, which comprises the following steps of: 1, collecting waste concrete, waste mortar and waste brick slag; 2, smashing and screening, namely smashing and screening the collected waste concrete, the collected waste mortar and the collected waste brick slag to obtain regenerative rough aggregates and regenerative fine aggregates; and 3, preparing foam concrete, namely firstly preparing cement slurry, namely uniformly stirring concrete, water, the regenerative rough aggregates and the regenerative fine aggregates to obtain the cement slurry, and secondly adding a foam dilution solution, namely adding the foam dilution solution formed by uniformly mixing a foaming agent and water into the cement slurry, and uniformly stirring to obtain the foam concrete. The steps of the process are simple; the investment cost is low; the process is simple, feasible and high in operability; the waste concrete, the waste mortar and the waste brick slag can be effectively reused; the economical benefit is outstanding; the produced foam concrete material is high in heat preservation performance; and the problems that the construction waste is abandoned and stacked randomly and occupies the land, the waste of resources is severe, and the environment pollution is severe are solved.

Description

technical field [0001] The invention belongs to the technical field of construction waste recycling, and in particular relates to a construction waste recycling process. Background technique [0002] All kinds of waste generated during the construction process of construction projects are collectively referred to as construction waste. In recent years, with the rapid development of the construction industry, more and more construction wastes are produced, which not only cause a lot of waste of resources, but also take up a lot of space, affect the urban environment, and bring a lot of inconvenience to people's production and life. Therefore, construction waste should be classified and collected, rationally treated and utilized at the construction site. Appropriate collection devices should be set up for different construction wastes, and they should not be incinerated, discarded, or mixed with domestic waste. Among them, the construction waste generated at the construction ...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a construction waste recovery and reuse process aimed at the deficiencies in the above-mentioned prior art. The effective reuse of waste mortar and waste brick slag has significant economic benefits, and the foamed concrete material produced has good thermal insulation performance, which can effectively solve many practical problems such as random dumping of construction waste and land occupation, serious waste of resources, and large environmental pollution.
