Abstract

The invention relates to a preparation method of a lightweight self-thermal insulation building block containing abandoned brick particles and abandoned foams. The preparation method comprises the following steps: crushing abandoned materials, preparing a cavity module, and preparing and maintaining a precursor. According to the preparation method of the self-thermal insulation building block, the subsidence problem caused by too high water absorption of the cavity module when the cavity module is dried and then is subjected to internal casting is avoided, and the problem that single brick aggregate is poor in strength after building wastes are regenerated in the prior art is effectively solved. The preparation method disclosed by the invention has the advantages of high volume stability, simple preparation process, low requirement to equipment, low production cost, no discharge of wastewater and waste gas, capability of effectively and comprehensively utilizing the building waste, energy conservation and environmental friendliness.

Description

technical field [0001] The invention relates to the technical field of preparation of environment-friendly self-insulating blocks, in particular to a method for preparing light-weight self-insulating blocks containing waste brick particles and waste foam. Background technique [0002] The acceleration of urbanization has promoted the demolition and reconstruction of a large number of original residences, resulting in a large amount of construction waste such as waste concrete slag powder, gravel, bricks, waste foam boards for external wall insulation, waste wood, etc. Among them, concrete, Bricks, waste foam boards for external wall insulation, etc. account for 40%-60% of construction waste. The current disposal methods are generally open-air stacking or landfill. These two methods not only waste resources and damage the ecological environment, but also occupy land resources. , so construction waste resource treatment and utilization has become a major social issue. [0003...
