Anti-clogging performance of pervious concrete incorporating hydrophobic agent

The clogging of pervious concrete has always been a concern for many researchers. Hydrophobic agents were added in the pervious concrete in this study to improve its anti-clogging performance based on the lotus effect. Mechanical performance, permeability performance, and anti-clogging performance of pervious concrete were evaluated. The results show that the addition of hydrophobic agents in pervious concrete improved the compressive strength, while the permeability performance was reduced to a certain extent. The anti-clogging performance was significantly improved, indicating that hydrophobic agents may become an effective measure to improve the anti-clogging ability of pervious concrete.
