Abstract

The invention relates to a formula of an environment-friendly hollow brick and particularly relates to a formula for manufacturing the hollow brick from waste coal ash and belongs to the technical field of bricks for buildings. The hollow brick comprises the following components: 40-50 parts of brick coal ash, 15-20 parts of waste plastic, 5-8 parts of plaster, 10-15 parts of gelatin, 1-2 parts of an early strength agent, 1-2 parts of calcium formate, 1-2 parts of sulfate and 1-2 parts of sodium lauryl sulfate. The hollow brick is simple in formula and has long service life, the manufactured finished product has the advantages of small porosity and high hardness; since the hollow brick is mainly prepared from coal ash used as a raw material, low production cost and resource conservation are achieved, the waste raw material is recycled and the hollow brick has certain significance for comprehensive utilization and development.

Description

technical field [0001] The invention relates to an environment-friendly sintered brick formula, in particular to a formula for making hollow bricks by using waste fly ash, and belongs to the technical field of building bricks. Background technique [0002] Sintered hollow brick, referred to as hollow brick for short, refers to the brick with vertical holes, the porosity is not less than 40%, the hole size is small and the number is large, and the shale, coal gangue or fly ash is used as the main raw material. Ash is industrial waste discharged from coal-fired power plants. Due to its large amount, it has become a serious environmental problem. The main oxide composition of fly ash is: SiO 2 、Al 2 o 3 , FeO, Fe 2 o 3 , CaO, TiO 2 Wait. 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 ...
