In this study,a graphene oxide modified pervious concrete was developed by using a low-reactivity,high-calcium fly ash as sole binder,chemical activators and other admixtures.The density,void ratio,mechanical strength,infiltration rate,Youngs modulus,and degradation resistance of pervious concrete were measured against other three controlled groups.The test results indicated that the graphene oxide modified fly ash pervious concrete is comparable to the Portland cement pervious concrete.While the addition of 0.03%graphene oxide(by weight of fly ash)increased the compressive strength,split tensile strength,Youngs modulus and degradation resistance of fly ash pervious concrete noticeably,the void ratio and infiltration rate were reduced.
