Recycled aggregate water permeable brick and manufacturing method thereof

Abstract

The invention discloses a recycled aggregate water permeable brick which comprises a base layer structure and a surface layer structure. The base layer structure accounts for 91% of the overall thickness of the water permeable brick, and the surface layer structure accounts for 9% of the thickness of the water permeable brick. The base layer structure is prepared from the following components in percentage by mass: 50-60 percent of waste recycled aggregate broken from an old road concrete layer, 5-10 percent of cement, 5-0 percent of DHT, 5-15 percent of water, 20-30 percent of sand and 1 percent of composite reinforcing agent A; and the surface layer structure is composed of the following components in percentage by mass: 1-5% of a cementation enhancer B, 3-5% of a heat reflection material, 10-20% of quartz sand, 50-60% of cement and 10-30% of water. According to the scheme, the recycled aggregate water permeable brick which is high in water permeability, high in strength, high in fracture resistance, free of radiation, resistant to alkali and attractive is obtained while the problem of waste disposal of the old road concrete demolition is solved, the ecological environment is protected and the requirements of sponge city construction are met.

Description

technical field [0001] The invention belongs to the field of making permeable bricks, in particular to a method for making permeable bricks made of recycled aggregates. Background technique [0002] In the municipal construction of the city, impermeable ground materials cannot allow rainwater to seep into the ground, resulting in a drop in the groundwater level, and urban waterlogging is prone to occur in case of heavy rain; The cyclic exchange of heat makes it difficult to regulate the surface temperature and humidity, and together with the road structure, forms the urban "heat island effect". Therefore, in the construction of sponge city, a large number of road bricks with water permeability function are needed. However, the ordinary permeable step bricks in the prior art have the disadvantages of poor water permeability and low strength, and it is difficult to meet the needs of sponge city construction. [0003] In the process of urbanization, the municipal infrastructu...

Problems solved by technology

However, the ordinary permeable bricks in the prior art have the disadvantages of poor water permeability and low strength, and it is difficult to meet the needs of sponge city construction.

[0003] In the process of urbanization, the municipal infrastructure is also developing rapidly at the same time, and the waste from old road demolition and maintenance is increasing, which is usually disposed of by open-air stacking or direct landfill, which consumes a lot of land acquisition fees, garbage removal and transportation fees, etc. At the same time, problems such as dust, dust and sand flying in the process of clearing, transporting and stacking have once again caused serious environmental pollution
