Abstract: Pervious concrete is a unique and eco-friendly alternative to traditional concrete, known for its high porosity and permeability. Different mix designs, with and without fines, were tested to determine their mechanical properties. The study found an inverse relationship between compressive strength and permeability. Various mixtures were evaluated using aggregate sizes ranging from 12 mm to 4.75 mm, with consistent water content and varying fines content. Pervious concrete typically exhibits compressive strength between 9.18 MPa and 14.06 MPa, and permeability ranging from 5.9% to 12.7%. The desired void ratio falls between 15% and 20%. The study emphasizes the influence of factors like shape, angularity, paste content, size, and water-to-cement ratio on the strength and permeability of pervious concrete. The goal is to implement pervious concrete in different applications to replenish groundwater resources
