Porous concrete plays a crucial role in the construction of sponge cities, which are designed to exhibit exceptional "resilience" in adapting to environmental changes and responding to natural disasters. Like sponges, these cities absorb, store, infiltrate, and purify water during rainfall, and then release and utilize the stored water as needed. Many cities achieve this water-absorbing function during rainfall 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.
