Analysis of Mechanical Properties and Permeability of Recycled Aggregate Permeable Concrete
Recycled aggregate permeable concrete specimens with different water cement ratio and amount of added aggregate have been done,and the cubic compressive strength and permeability performance of these specimens after 28 d standing curing.Experimental results showed that compressive strength and permeability performance of permeable concrete increase first and then decrease with increasing of cement ratio,and compressive strength decreases with increasing of amount of added aggregate while the permeability performance not much changes.Final-ly,the optimum proportion of recycled aggregate permeable concrete with water cement ratio of 0.25,amount of added aggregate of 15%,ag-gregate binder ratio of 1︰4,water reducing agent of 1.5%and silicon powder of 6%is proposed,which provides technical guidance for the practical application of pervious concrete.
