Porous concrete pavement materials are eco-friendly, high-permeability materials used in sponge city construction. They serve as a novel paving method that can partially replace urban paved surfaces, effectively improving the urban ecosystem. This material revives the urban ground surface, allows rainwater to infiltrate the ground, effectively eliminates surface water accumulation, and is a green, breathable ground material.

Porous concrete paving is composed of aggregates, cement, and water, often using single-size or intermittent-size coarse aggregates as the framework, with the fine aggregate content generally controlled within 20% of the total aggregates. Cement options include silicate cement, ordinary silicate cement, and slag silicate cement; admixtures are selected from the special reinforcing agents produced by Shanghai Jingqi Landscape Technology Co., Ltd.

When batching, first add cement, admixture, and coarse aggregate, then add half the water required, mix for 30 seconds; subsequently, add the additive, mix for 60 seconds; and finally, add the remaining water, mix for 120 seconds before discharging. Permeable paving has been researched and applied in the United States since the late 1970s and early 1980s. Many countries have been extensively promoting its use, such as Germany, which expects to convert 90% of its roads to permeable paving in the short term. This change aims to alter the past practice of ground paving that damaged urban ecosystems, thereby providing the permeable paving surfaces with significant social benefits.

Porous pavement, as a new eco-friendly and ecological road material, is gaining widespread attention. In modern cities, the ground surface is often covered with reinforced concrete buildings and impermeable roadways, 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 of nature's destruction. However, by creating continuous voids, a connection point with the natural environment can be established.

As an environmentally friendly concrete with reduced load, permeable paving is a creative material for improving and restoring the damaged earth environment, allowing human life to coexist harmoniously with nature and to develop sustainably.
