PARTIAL REPLACEMENT OF CEMENT BY FLYASH IN POROUS CONCRETE

Many places were covered with impermeable surfaces like cement concrete and bitumen it leads to major impact on the ground water table. Pervious Concrete pavement is an effective way to minimize this issue. Pervious concrete is an open graded structure with interconnected voids through which rain and storm water is permitted. Pervious concrete is one of the most effective pavement surface to improve ground water level. Porous concrete is an innovative material which is a mixture of coarse aggregate, cement, water and little amount of sand or no sand along with or without chemical admixtures. Porous concrete is a new concept to increase the ground water table level. The main aim of this work is to study the compressive strength of porous concrete by replacing the cement by fly ash.
