Experimental Analysis of Pervious Concrete

Abstract

The performance of pervious concrete that uses fly ash and metakaolin as partial cement substitutes is assessed in this study. Pervious concrete is broadly recognized as an eco-friendly material that supports groundwater recharge and helps manage storm water. The goal of the study is to increase compressive strength while preserving sufficient porosity and permeability. Eight different mix designs containing different ratios of cement, coarse aggregate, and additives were tested. After seven and twenty-eight days of curing, compressive strength and porosity were assessed. According to the findings, a well-balanced mixture of fly ash and metakaolin considerably increases compressive strength without sacrificing permeability. The results lend credence to modified pervious concrete’s possible application in environmentally friendly urban infrastructure.
