Porous concrete plays a crucial role in the construction of sponge cities, which are cities that exhibit exceptional "resilience" in adapting to environmental changes and responding to natural disasters. Like sponges, they absorb, store, infiltrate, and purify water during rain, and then release and utilize the stored water as needed. Many cities achieve this water-absorbing function during rain by laying porous concrete on urban roads. After using ecological porous concrete for road construction, it not only increases the permeable and breathable area of the city, regulates the urban climate, reduces ground temperatures, but also helps alleviate the urban "heat island" phenomenon.
