Abstract

The invention relates to a method for manufacturing high-strength flame-retardant-type light wall body bricks by utilizing construction waste, wherein the method comprises the following steps of: A. sorting waste construction concrete and waste tiles, and crashing to form particles of 1.5mm-2mm; B. blending and stirring the construction waste particles, water, cement, plaster, powder coal ash, epoxy resin, asbestos and aluminum oxide according to the following ratio respectively by mass percent: 70%-73%, 11%-13%, 6%-8%, 1%-2%, 3%-4%, 2%-3%, 2%-3% and 2%-3%; and C. placing a green body formed after stirring into a hydraulic molding machine, pressing and molding. The bricks manufactured by the method provided by the invention have the advantages of high strength, good fire resistance performance and the like, and play roles of resource protection and environment protection.

Description

technical field [0001] The invention relates to a method for making bricks from construction waste, in particular to a method for making high-strength flame-retardant lightweight wall bricks from construction waste. Background technique [0002] With the continuous acceleration of urbanization, the generation and discharge of construction waste in cities is also increasing rapidly. While enjoying urban civilization, people are also suffering from the troubles caused by urban garbage. Among them, construction waste accounts for a considerable proportion, accounting for 30% to 40% of the total garbage. Therefore, how to deal with and utilize more and more waste Construction waste has become an important issue faced by government departments at all levels and construction waste disposal units. [0003] Many wastes in construction waste can be reused as renewable resources after being sorted, removed or crushed. Among them, the waste construction concrete and waste bricks are u...
