This study examines the effect of adding metakaolin at different percentages on the compressive strength of pervious concrete. Pervious concrete is a type of concrete with high porosity that allows water to pass through, reducing runoff. Metakaolin was added at 1%, 1.5%, 2%, and 2.5% of the concrete weight. Concrete cubes were made and tested for compressive strength after 7 and 28 days of curing. The results showed that compressive strength generally increased with metakaolin content up to 2%, with the 2% mix achieving the highest strength of 21.2 MPa at 28 days. Above 2%, the strength decreased slightly. Therefore, adding up to 2% metakaolin improved the
