Abstract

The invention belongs to the technical field of building materials and provides a fly ash colorful brick and a preparation method. The fly ash colorful brick comprises, by weight, 35-51 parts of fly ash, 8-14 parts of calcium sulfate, 6-17 parts of gypsum, 1.05-3.04 parts of sodium silicate, 15-23 parts of pigment, 5-19 parts of adhesive and 7-20 parts of water. The fly ash colorful brick solves the problem about fly ash recycling. The provided preparation method of the fly ash colorful brick shortens the production period, sintering and heat energy are not needed, time is saved, the productivity is improved, the cost is reduced, and more importantly, the environment pollution problem caused by fly ash can be relieved.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a fly ash colored brick and a preparation method thereof. Background technique [0002] Fly ash is one of the largest industrial wastes in my country. 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 human beings and organisms. In addition, fly ash can be used as an admixture for concrete. [0003] my country is a large coal-producing country, and coal is used as the basic fuel for electric power production. my country's energy industry has developed steadily, with an annual growth rate of 7.3% in power generation capacity. The rapid development of the power indu...
