Methods of improving performance on pervious concrete

In order to improve the performance of pervious concrete,by using the single factor test method this paper systematically researched the effects of compressive strength and permeability coefficient of pervious concrete along with the changes of shaping method,mass ratio of water to cement,mass ratio of aggregate to cement,particle size of aggregate and the dosage of polymer.The results indicate that the appropriate shaping method and parameters can achieve high performance of permeable concrete,mass ratio of aggregate to cement and particle size of aggregate are the key factors affecting the compressive strength of pervious concrete,mass ratio of water to cement has minor effect on the compressive strength and major effect on permeability coefficient of pervious concrete,combining with polymer can improve the performance of pervious concrete.
