Experimental study of the physical and mechanical properties of pervious concrete with recycled and gravel aggregate

A experiment research on pervious concrete using recycled and gravel as aggregate was carried out. The effects of aggregate binder ratio and water cement ratio on compressive strength of the concrete were studied. The results show that the water cement ratio has different influence on the compressive strength of the two kinds of concretes, while the influence rule of the aggregate binder ratio is approximately the same, but the degree is different, moreover, the compressive strength of the concrete (using gravel as aggregate) in 28 days is basically the same as that in 56 days.
