Abstract

Significant research and development have occurred for pervious concrete, but its acceptance in cold climates is still limited. Vulnerability to freeze-thaw and salt exposure has led to uncertainty about its long-term performance. Additionally, the current standardized freeze-thaw testing procedure is not recommended for pervious concrete, as it is not representative of field conditions. This study employed testing processes that are more representative of field conditions to determine the effects of the inclusion of sand as a fine aggregate; fly ash, slag and silica fume as cementitious alternatives, and construction practices on freeze-thaw durability and deicing salts exposure of pervious concrete. The use of pervious concrete itself is considered a best management practice in stormwater management; possibility of substituting cement with a waste product such as fly ash, slag and silica fume promotes sustainability even further.
