Abstract

Pervious concrete is a sustainable pavement with high permeability. The purpose of this study is to evaluate physical and mechanical properties of different mixes of pervious concrete. Enhancing mechanical properties of pervious concrete is essential, as its low density gives low compressive strength. Effect of polypropylene fiber and Industrial waste material addition on physical and mechanical pervious concrete properties is presented. Also, effect of using Adicrete-B2 admixture was compered to usage of viscocrete admixture on pervious concrete properties. Test results showed that using polypropylene fiber improves compressive strength and water permeability of pervious concrete compered to control mix. Industrial waste material improves mechanical properties till 10% replacement of cement, then it decreases. Increasing industrial waste material replacement ratio improves clogging resistance. splitting-tensile strength of pervious concrete equal 15-20 % of compressive strength and flexural strength equal 20-25 % of compressive strength same as traditional concrete. Adicrete-B2 admixture gives best results of mechanical properties and clogging resistance compared to other mixes.
