Abstract

The invention discloses a porous permeable brick with purification function and a preparation method thereof. The permeable brick comprises the following components by weight: 40-60 parts of waste glass, 40-60 parts of fly ash, 20-30 parts of cement, 5-10 parts of montmorillonite, 5-10 parts of sisal fiber, and 10 parts of gypsum. ~15 parts, 0.5-1 part of sodium lignosulfonate, 0.5-1 part of triterpene saponin, 0-0.5 part of microbial bacterial liquid, 1-5 parts of aggregate, and 5-10 parts of binder. The invention combines solid waste reduction treatment with resource utilization, reduces the use and consumption of traditional building materials with high energy consumption and high emission, and has better environmental protection and economic benefits.

Description

technical field [0001] The invention belongs to the technical field of concrete preparation, and in particular relates to a porous permeable brick with purification function and a preparation method thereof. Background technique [0002] Fly ash is the fine ash collected from the flue gas after coal combustion. Fly ash is the main solid waste discharged from coal-fired power plants. The main oxide composition of fly ash in thermal power plants in my country 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 will generate dust and pollute the atmosphere; if it is discharged into the water system, it will cause river silting, and the toxic chemical substances in it will also cause harm to the human body and organisms. How to effectiv...
