Abstract：The new lotus leaf hydrophobic agent was introduced to the research of pervious concrete.The results show that hydrophobic agent used in pervious concrete is feasible.The compressive strength will be improved after adding hydrophobic agent,the optimum parameters of hydrophobic concrete were the goal porosity 20％,water cement ratio 0.28,hydrophobic agent 4％.The analysis shows that when the effective porosity is more than 23.8％,the permeability coefficient of hydrophobic concrete will exceed its not added.The microstructure of hydrophobic concrete added hydrophobic agent is more compact and have uniform waxy small salient,which formed the lotus-effect.
