Permeable concrete is a special concrete which consists of cement, coarse aggregate and water. Due to rapid growth of globalization and urbanization, the construction of concrete roads increasing day by day which leads to decrease in percolation of storm water, surface runoff occurring to the decrease in ground water table. In previous concrete, single sized aggregate is used to maintain the void ratio in the concrete. The cement paste is bonded with aggregate with a void ratio of 20%. In this investigation, concrete of M20 grade with water cement ratio of 0.38 is used. The properties of concrete were increased by using Rice husk ash and Bagasse ash in changed percentages (10%, 20%, 30%) by weight of cement and with the combination of rice husk ash and bagasse ash 10% (5%RA + 5%BA), 20%(10%RA+10%BA), 30%(15%RA+15%BA) are used. The compressive strength of cubes, split tensile of cylinders are casted, tested after 7 days and 28 days. After testing, the optimum percentages of replacement of admixtures are found in the Permeable concrete. Therefore the strength and durability properties of permeable concrete with the addition of bagasse ash and rice husk ash with partial replacement of cement are compared with conventional concrete.
