Abstract

The invention relates to a formula and a production method of an environmental-friendly fly ash insulating brick. Fly ash, cement, mica powder, clay, a hydrosol, a defoaming agent, desulphurization gypsum, perlite, asbestos and aggregate chips are taken as main raw materials. The production method comprises the following main processes: material selection, smashing, burdening, preparation, drying, burning and finished product obtainment. The formula and the production method have recycling capability, can be used for saving sources and are convenient for production.

Description

Technical field: [0001] The invention relates to the field of building materials, in particular to a formula and a production method of a green and environment-friendly fly ash thermal insulation brick. Background technique: [0002] At present, fly ash is one of the industrial wastes with a large discharge volume in my country, and the annual discharge volume of my country's slag has reached 30 million tons at this stage. With the development of the power industry, the discharge of fly ash from coal-fired power plants is increasing year by year. If a large amount of fly ash is not treated, it will generate dust and pollute the atmosphere. If it is discharged into the water system, it will cause river silting, and the toxic chemicals in it will also cause harm to humans and organisms. Therefore, the processing and utilization of fly ash has attracted widespread attention. Advantages of using fly ash Adding fly ash in concrete saves a lot of cement and fine aggregate; inc...
