Ecological pervious concrete in revetment and restoration of coastal Wetlands: A review

Impermeable cement in revetment walls interferes with the Earth's hydrologic cycle and impedes substance exchange between the sea and land. Ecological pervious concrete (EPC) could be used for ecological revetment. EPC has a complex pore structure that allows precipitation to seep into the ground or feed into rivers, while also providing a living space for plants and animals. This comprehensive review evaluates the past two decades of research on the use of EPC in revetment and restoration in coastal wetlands. The mechanical properties, durability, and ecological compatibility of EPC, and benefits of EPC to hydrological and biological connectivity are discussed. Future research should concentrate on the interface transition zone and bonding state between aggregates in EPC to improve its properties. Vegetation compatibility evaluation standards need to be clear to guide further research in coastal wetlands and also in other locations where the Earth's hydrologic cycle is negatively affected by pavement.

Automated summary

Ecological pervious concrete (EPC) can be used for ecological revetment, allowing precipitation to seep into the ground and providing a habitat for plant growth. Future research should focus on improving the properties of EPC and establishing clear vegetation compatibility evaluation standards.
