Ecological pervious concrete in revetment and restoration of coastal Wetlands: A review
Graphical abstract Display Omitted
Highlights Technical requirements for EPC differ obviously among the three coastal wetland zones. Pore structure and aggregate bonding state dominate EPC’s mechanical property. Mineral admixture is benefit to EPC’s durability and vegetation compatibility. Uniform criteria is urgent need for evaluating EPC’s ecological function. Study on interfacial transition zone in EPC will become research focus in future.
Abstract 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.
