According to this ratio, permeable concrete can be called porous concrete and drainage concrete. It can repair the defects of pavement, let rainwater flow underground and quickly replenish groundwater. Permeable concrete consists of crushed stone, water and special cementing agent.
It can be made into concrete pavement, slope protection and its products, which can achieve the effects of drainage, anti-skid, sound absorption, noise reduction and water seepage, improve the ecological cycle of the surface, facilitate traffic safety, protect the living environment and solve the negative impact brought by large-scale modern city construction. Engineering practice has proved that permeable concrete is a new type of multifunctional pavement material.
Advantages of permeable cement concrete
Increasing the permeable and breathable area of the city, strengthening the heat and moisture exchange between the surface and the air, regulating the urban climate and lowering the surface temperature are conducive to alleviating the urban heat island phenomenon, improving the growth conditions of ground plants and soil microorganisms and adjusting the ecological balance. Make full use of rain and snow precipitation, increase the relative humidity of the surface, supplement the increasingly depleted groundwater resources in the urban area, and give play to the reservoir function of permeable subgrade.
It can reduce the burden of road drainage system in rainy season and obviously reduce the pollution of urban water bodies caused by heavy rain. Absorb the noise generated when the vehicle is driving, create a quiet and comfortable living and traffic environment, and prevent water accumulation on the road in rainy days and reflection at night. It has good wear resistance and skid resistance, effectively prevents pedestrians and vehicles from slipping, and improves the comfort and safety of vehicles and pedestrians.
