Problems solved by technology

[0004] The purpose of the present invention is to provide a method for making bricks from construction waste. By using modified epoxy resin and silicic acid sol as bonding and curing materials, the bricks produced have better comprehensive performance, which solves the problem of the general problem of the construction waste brick making method. The use of cement as the adhesive has a relatively large proportion, high cost, and the problem that construction waste with high soil content cannot be used

Abstract

The invention discloses a method for preparing a brick from building garbage, and relates to the technical field of building garbage recycling. The method comprises: SS01, preparing the following rawmaterials by weight: 32-40 parts of building waste, 35-45 parts of engineering residue oil, 30-35 parts of coal residue, 30-35 parts of slaked lime, 5-15 parts of a silicic acid sol, and 10-20 parts of an epoxy resin; and SS02, adding the raw materials of the step SS01 to a strong mixer, mixing, adding water, and uniformly stirring, wherein the water adding amount is controlled at 10-20%. According to the present invention, by using the modified epoxy resin and the silicic acid sol as the bonding and curing material, the produced brick has advantages of good fire resistance, high-temperature resistance, anti-impact flexibility, improved brittleness and good comprehensive mechanical property, wherein the proportion of the aggregate component is low, such that the cost is reduced so as to achieve the good prospect.

Description

technical field [0001] The invention belongs to the technical field of construction waste recycling, in particular to a method for making bricks from construction waste. Background technique [0002] Most of the construction waste is reclamation without any treatment. However, due to the shrinking of the reclamation project, the construction waste is transported to the suburbs or villages in batches, and is disposed of by open-air stacking or landfill. Lots of land. The places where construction waste has been landfilled can never be recultivated, resulting in a serious waste of land resources. [0003] At present, the reuse of construction waste can effectively solve the problem of waste of resources. The more effective way is to use construction waste to make bricks. There are still a series of problems in the existing construction waste brick production methods. Cement is generally used as the adhesive, which accounts for a large proportion. , the cost is high, and the ...
