Because of its special skeleton-pore structure,ordinary pervious concrete has poor mechanical properties compared with ordinary concrete.Under this special structure,the adhesion between the aggregate and the cementitious material is an important factor affecting the quality of its various properties.The polymer admixture can effectively improve the bonding effect between the two.Aiming at this problem,it mainly briefly describes the effect of adding polymer materials on the mechanical properties,water permeability and durability performance of permeable concrete,analyzes and summarizes the effect of polymer modified pervious concrete on the performance,and proposes future research in this field.Make certain suggestions and prospects.
