Experimental Studies on Strength and Permeability Characteristics of Fiber Reinforced Pervious Concrete Incorporating GGBS
Abstract: Pervious concrete is increasingly recognized as a sustainable construction material for mitigating urban flooding, enhancing stormwater management, and promoting groundwater recharge. This study investigates the performance of fiber reinforced pervious concrete (FRPC) incorporating Ground Granulated Blast Furnace Slag (GGBS) as partial cement replacement, with polypropylene fibers (0.2%) to improve mechanical properties. Experimental evaluation was conducted on mixes with varying GGBS percentages (20%, 40%, 60%) and aggregate sizes (20 mm, 13.2 mm, 10 mm). Tests included fresh properties, compressive strength, split tensile strength, flexural strength, and permeability using codal provisions (IS?516:1959; IS?5816:1999; IS?3085:1965). Results indicate that 20% GGBS replacement with 0.2% polypropylene fibers provides the optimum balance between strength and permeability, achieving compressive strength of 18.1?MPa and split tensile strength of 4.5?MPa at 28 days, while maintaining adequate permeability (5.3???10-3?m/s). Beyond 20% replacement, strength declined due to reduced cement content and slower hydration, while permeability decreased with higher GGBS levels owing to finer particle packing. The findings highlight the potential of FRPC with controlled GGBS incorporation to reduce cement consumption, lower embodied carbon, and support sustainable pavement applications.
