Porous concrete, as a new environmentally friendly and ecological road material, is increasingly attracting attention. Modern urban surfaces are often covered with reinforced concrete buildings and impermeable pavements, lacking the breathability, heat absorption, and rainwater permeability of natural soil. This leads to a series of environmental issues, and concrete has long been considered a culprit in nature's destruction. However, by forming continuous voids, a connection point with the natural environment can be created.

Porous concrete, sand-free concrete, etc., [1] are made by uniformly mixing aggregates, binders, additives, cement, and water to lay them out as pavement. They offer higher strength and durability than traditional concrete, meeting the requirements for structural mechanical properties, functionality, and service life. They are also harmonious with the natural environment, reducing the burden on the Earth and ecological systems, and enabling the recyclability of non-renewable resources. Additionally, they provide excellent usability, creating a gentle, comfortable, and convenient living environment for humans.
