What benefits does the permeable floor bring to the city

Compared with traditional concrete, permeable floor has higher strength, better durability, good physical and mechanical properties and chemical resistance. Permeable floor is also called permeable concrete, permeable floor, permeable concrete, and sandless concrete. It is a kind of concrete floor with good water permeability formed by uniformly mixing and paving the road surface by cement, gravel, binder and water. .
1.1 It has high water permeability: the porosity of permeable concrete pavement is 15%-25%, and the water permeability can reach 30-52L/m.h, which is much higher than the discharge rate of the most effective drainage configuration.
The permeable floor solves the problem of easy accumulation of water on the road, improves the safety and comfort of people and vehicles walking, and improves the traffic road conditions and people's living environment. At the same time, rainwater quickly seeps into the ground, effectively replenishes groundwater, alleviates the "heat island effect" of the city, and protects the city's natural water system from damage, which has a good environmental value.
1.2 Strong bearing capacity: According to relevant testing and appraisal, the bearing capacity of permeable concrete pavement can reach the bearing standard of C10～C30 concrete, which is higher than the bearing capacity of general permeable bricks. Colored permeable concrete can be used in the road surface of light-loaded motor vehicles such as parking lots, municipal sidewalks, and fire passages.
1.3 Freeze-thaw resistance: the permeable concrete structure itself has a larger porosity, and the pavement paved with it has stronger freeze-thaw resistance than ordinary concrete pavements. The freeze-thaw resistance index is 1.01, which will not be affected by freezing and thawing. A face fracture occurs.
1.4 Good decorative effect: The permeable concrete system has high-quality materials such as primary colors, colored cements, exposed cements and colored surface protective agents. In the past, the single color of concrete was gray. On the basis of retaining the characteristics of traditional concrete, the permeable floor gave it new connotations. The colors were colorful and diverse. The use of different colors to integrate the building and the landscape creates a beautiful and warm living environment. Therefore, the permeable floor becomes an indispensable part of the future city construction, showing the beauty of the city.
1.5 Economic durability: The durability and wear resistance of permeable concrete is higher than that of ordinary bitumen, and at the same time, it avoids the shortcomings of ordinary permeable bricks such as short service life and poor economy.
Permeable floor is an important paving material in the low-impact development system of sponge city. It can be coordinated with the natural environment to reduce the environmental load. It also has good functions and can bring people a mild, comfortable, warm and convenient living environment.
