With the acceleration of urbanization, urban surface hardening has led to a decrease in rainwater infiltration capacity, causing environmental problems such as waterlogging and a decrease in groundwater level.
Therefore, building “sponge cities” has become a goal for more and more cities.
Permeable concrete, as a new type of eco-friendly building material, has a special pore structure that can effectively discharge surface water, alleviate urban heat island effect and waterlogging, and has been widely used in urban roads, squares, parking lots and other projects.
