High-strength water permeable brick and production process thereof

Abstract

The invention relates to a high-strength water permeable brick and a production process thereof. The high-strength water permeable brick comprises a sand-based surface layer and a cement concrete structure layer, and the sand-based surface layer comprises, by weight, 80 parts of coated sand, 8 parts of polyethersulfone resin, 3 parts of glass fiber, 30 parts of epoxy resin and 10 parts of alkali lignin; and the cement concrete structure layer comprises, by weight, 60 parts of cement, 50 parts of fly ash, 85 parts of quartz sand, 30 parts of pitchstone powder, 5 parts of yellow dextrin, 7 partsof polypropylene fiber, 3 parts of a water reducing agent and 50 parts of water. By reasonably controlling the components and contents of the sand-based surface layer and the cement concrete structure layer, the prepared high-strength water-permeable pavement brick is excellent in water permeability, good in high-temperature resistance, excellent in wear resistance and skid resistance and high inflexural and compressive strength.

Description

technical field [0001] The invention relates to the technical field of production of permeable bricks, in particular to a high-strength permeable brick and a production process thereof. Background technique [0002] With the development of the economy, the surface of modern cities is more and more covered by buildings and concrete. This "hardening" of the surface makes it difficult for atmospheric precipitation to penetrate into the ground in time, and the surface runoff increases, forming the "heat island effect". As well as environmental problems such as waterlogging and urban surface subsidence caused by insufficient drainage. As an environmental material, porous permeable bricks are applied to the paving of roads and squares, which can allow part of the precipitation to infiltrate into the ground and reduce surface runoff, thus better solving the above problems. The currently prepared permeable bricks have insufficient compressive strength, are easy to crack, and have p...

AI Technical Summary

Problems solved by technology

The currently prepared permeable bricks have insufficient compressive strength, are easy to crack, and have poor flexural properties. At the same time, the existing permeable bricks usually include a sand-based surface layer and a cement concrete structure layer. The raw materials used are the coated sand preparation process. The stirring tank is used to heat up, keep warm and cool down, then stir evenly, cool to room temperature, and crush and sieve. In the prior art, the stirring effect of the stirring tank is limited, resulting in long time required for the stirring reaction and poor mixing effect. As a result, the quality of the permeable bricks is greatly affected, and the phenomenon of poor compressive strength and easy cracking will appear accordingly, and the flexural performance is not good, so it needs to be improved
