In this study, pervious concrete specimens were created containing 100 percent of Recycled Coarse Aggregate (RCA) as a replacement for Natural Coarse Aggregate (NCA) and seawater as a replacement for Fresh Water (FW). Eighteen specimen tests in total were prepared which consisted of nine specimens containing Recycled Coarse Aggregate Seawater (RCAS) concrete and nine specimens containing Recycled Coarse Aggregate Fresh-water (RCAF) as control concrete. Both water to cement ratio of 0.45 and RCA to cement ratio of 0.25 is determined and the mix design is calculated. Fresh concrete was cast on the cylindrical mold of 150 x 300mm in a porous formation. Then the compressive strength and infiltration rate tests were conducted to understand the performance of RCA mixed seawater (SW) at curing times of 3, 7, and 28 days. The results show that the compressive strength of RCAS can reach a peak of around 8.98 MPa compared with RCAF just around 7.27 MPa in maximum curing of 28 days and the value of RCAS samples shows that the infiltration rate is increasing linearly as compressive strength is from three days to 28 days.
