Designing Porous Concrete to Resist Damage from Deicing Salts and Freeze-Thaw

Pervious concrete, with its ability to act as both a structural pavement and a stormwater mitigation system, has been identified as a best management practice (BMP) to efficiently manage stormwater runoff and reduce stormwater pollution. Despite the benefits and significant research and development on pervious concrete, its acceptance in cold climates is still limited. Vulnerability to freeze-thaw and salt exposure has led to uncertainty about its long term performance. The scope of this research is to: (1) evaluate in the laboratory porous concrete mixes for their resistance to deicing chemicals; (2) quantify the effects of sand addition on the resistance to deicing salts; (3) quantify the effects of fly ash replacement on resistance to deicing salts; (4) evaluate various chemical admixtures to determine if they improve resistance of porous concrete to deicing salts; and (5) determine how curing time affects resistance to deicing salts.
