Abstract

The strength of pervious concrete is relatively lower compared with ordinary concrete because of its porosity. In this paper, three reinforcing agents were used to optimize the performance of interface area between aggregate and cemented material. Specifically, the contents of FA were weight of cement 10%, 15%, 20% to replace cement; and similarly, the contents of BS were 5%, 8%, 10%; the contents of DLP were 1%, 3%, 5%. The ratio of aggregate (RAB) to binder was optimized for pervious concrete strength by experiment. The results showed that the compression strength of pervious concrete can be improved by adding suitable amount reinforcing agents such as FA, BS, DLP. The permeability coefficient and porosity of pervious concrete increased with the RAB increases. And there was a good linear relationship between permeability coefficient, porosity and RAB. The test results suggested that the suitable range of FA was 10%~15%, the range of BS was around 10%, and the range of DLP was 1%~3%. The results indicated that the best RAB was 3.5.
