Autoclaved aerated concrete brick manufactured from urban industrial solid waste and manufacturing method thereof

Abstract

The invention provides an autoclaved aerated concrete brick manufactured from urban industrial solid waste. The autoclaved aerated concrete brick manufactured from urban industrial solid waste comprises the following components by mass: 10.0-50.0 parts of activated carbon, 60.0-300.0 parts of blast furnace slag, 20.0-100.0 parts of steel slag, 30.0-150.0 parts of red mud, 100.0-500.0 parts of flyash, 60.0-300.0 parts of coal slag, 40.0-200.0 parts of waste gypsum, 25.0-125.0 parts of desulfurized ash, 45.0-225.0 parts of carbide slag, 35.0-185.0 parts of salt mud, 400.0-2000.0 parts of a cementitious material, 300.0-1500.0 parts of sand, 100.0-500.0 parts of stone and 60.0-300.0 parts of additives. The blast furnace slag, steel slag, red mud, fly ash, coal slag, waste gypsum, desulfurizedash, carbide slag and salt mud are crushed and processed for reutilization, then the processed materials are added into the concrete brick, thus not only realizing recycling of solid waste, but alsoeffectively preventing discarded solid waste from polluting the environment.

Description

technical field [0001] The invention relates to the technical field of waste recovery and reuse, in particular to a method for making autoclaved aerated concrete bricks by utilizing urban industrial solid waste and a manufacturing method thereof. Background technique [0002] With the development of industrial production, the amount of industrial waste is increasing day by day, especially in industries such as metallurgy and thermal power generation. The amount of industrial waste is huge, with various types and complex components. It is quite difficult to deal with it. Now only a limited number of industrial wastes are used. For example, the United States, Sweden and other countries have used iron and steel slag, Japan, Denmark and other countries have used fly ash and coal slag, other industrial wastes are still mainly stored passively, and some harmful industrial solid wastes are landfilled, incinerated, and chemically transformed. , microbial treatment and other methods ...
