Measurement of Permeability and the Correlation between Permeability and Strength of Pervious Concrete

Pervious concrete has been widely used in the fields of roads, buildings, water facilities as the material of drainage structure due to the excellent permeability. However, pervious concrete have relatively lower compressive and flexural strengths as compared to conventional concrete. Strength and permeability are two important design factors for pervious concrete, but limited research is conducted on their interactional relationship. This study focuses on the balance between permeability and strength properties of pervious concrete. A series of laboratory tests are conducted to demonstrate the effects of water-cement ratio, aggregate-cement ratio and porosity on the properties of pervious concrete including strength and permeability.
