Abstract

The invention discloses an environment-friendly brick prepared from solid waste solidified soil and a preparation method of the environment-friendly brick, the environment-friendly brick is prepared from the solid waste solidified soil, aggregate, fly ash, a cementing material, an additive and water according to a proportion through stirring, pressing and curing. The preparation method comprises the following steps: drying, crushing and screening solid wastes, and adding a curing agent according to the ratio for curing; the solid waste solidified soil, the aggregate, the fly ash, the cement, the additive and the water are mixed and stirred according to the proportion; and pouring the stirred mixture into a mold, and carrying out compression molding by using a press machine. The environment-friendly brick is convenient to manufacture, high in strength, low in water absorption rate and low in price, uses a large amount of solid waste and conforms to the national environment-friendly and energy-saving policy.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to an environmental protection brick prepared by using solid waste to solidify soil and a preparation method thereof. Background technique [0002] Bricks are an indispensable product in construction for thousands of years. Since ancient times, they have been sintered with clay, and later cement bricks, lime-sand bricks, aerated blocks, etc. all have a common feature: they are all made of clay, sand, stone, lime, cement and other resources. [0003] With the rapid advancement of urbanization, the construction of a large number of high-rise buildings and subways has produced a large amount of waste mud. Since the soil cannot directly react with the cement to make bricks, and the deep mud cannot directly plant trees and grass, it cannot be transported to landfill in large quantities. Urban engineering waste sludge and river sludge have become new problems in ur...
