A preparing method for water permeable bricks by utilizing building waste

Abstract

The invention belongs to the field of the reutilization for building waste resource and building material and provides a preparing method for water permeable bricks by utilizing building waste. The water permeable brick comprises a base and surface layer. The raw material of the base layer comprises, by weight: 50-60% of waste raw material crushing particles, 10-20% of slag powder, 5-15% of fire coal powder, and 20-30% of water. The raw material of the surface layer comprises, by weight: 10-20% of epoxy resin, 5-15% of carbon fiber, 10-20% of fine sand, 5-10% of heat reflection material, 30-50% of cement, and 10-20% of water. After the semi-finished product water permeable brick is prepared by mixing and optimizing the configuration, the semi-finished product water permeable brick is shaped by secondary material distribution and once excitation through the intelligentized device. The building water permeable brick has advantages of high permeability, permeation coefficient >= 1.0 * 10<-2 > cm/s, high strength, flexural quality which reaches the national standard of the quality of the brick, ecology, environmental protection, non-radiation, alleviating the city heat island effect,effectively reducing the temperature of the pavement by 3-7DEG C, the texture of natural stone, alkali resistance, and changing building waste into valuables and protecting the ecology environment.

Description

technical field [0001] The invention relates to the field of reuse of construction waste resources and building materials, in particular to a method for making permeable bricks by using construction waste. Background technique [0002] With the acceleration of industrialization and urbanization, the construction industry is also developing rapidly, and the accompanying construction waste is increasing. The amount of construction waste in China has accounted for more than 1 / 3 of the total urban waste. , but its production and reuse have not attracted much attention, and are usually directly disposed of in open-air stacking or landfill. It consumes a lot of construction funds such as land acquisition fees and garbage removal and transportation fees. At the same time, problems such as dust and dust flying during the removal and stacking process have caused serious environmental pollution. [0003] "Waterlogging every time it rains" has become a common problem in my country's c...

Problems solved by technology

However, ordinary permeable bricks in the prior art: porous concrete materials made of ordinary crushed stone are pressed and formed, and have the disadvantages of poor water retention and low strength, which are difficult to meet the needs of sponge city construction
