Pervious concrete mostly constitutes of single sized coarse aggregates and binders with less or no fine aggregate particles resulting in interconnected voided structure. However, the strength and durability performance of pervious concrete are less due to crack propagation through voids. The objective of this study is to investigate the effect of ground granulated blast furnace slag (GGBS) on the performance of pervious mixes with 12.5 and 20 mm single sized coarse aggregates. GGBS content was varied with proportions ranging from 0 to 50% at 10% intervals based on cement weight. The pre-pared mixes were subjected to experiments to identify the mix properties, functional properties and mechanical properties. The mechanical properties namely compressive strength, split tensile strength and flexural strength were increased by 22.96%, 15.45% and 15.34% respectively for 40% inclusion of GGBS in par with the reference mix. Inclusion of GGBS can decrease the cement consumption for pervious concrete production with sub-stantial improvement in mechanical properties.
