In this study, the durability of pervious concrete, with or without the crushed seashells, are studied by: freeze-thaw resistance test with and without deicing salt, clogging test and leaching test. The shell pervious concrete was created by replacing 60% mass of the natural aggregates in control pervious concrete by crushed seashells.

Durability: Resistance to internal forces resulting from freezing and thawing or wetting and drying cycles, as well as physical wear. This resistance comes from both density (fewer cracks and voids) and strength. Expansive forces generated in voids and fissures can be tremendous and lead to the disintegration of aggregate particles.
