Experimental Study on Pervious Concrete Pavement Using Recycled Material and Superplasticizer

The importance of pervious pavement concrete in reducing urban stormwater runoff and improving water quality is growing. Water and air can easily percolate through it that reduces the chances of inundation. The pervious concrete contains coarse aggregate including recycled coarse aggregate, the role of super plasticizer which enhance the compressive strength by reducing the water. One percent superplasticizer can reduce the water up to 20% to 40%. Concrete can sustain high strength in compression due to its voids; 10-25 percent of voids stand as its exceptional characteristics in good compression strength and overall performance. Porous concrete, permeable concrete, no-fines concrete and porous pavement are all terms for pervious concrete. Water can move through the system due to its porous nature. It is made by combining a single aggregate size with cement and a little quantity of admixture, with little or no fine aggregates. The pervious pavement concrete will contain course aggregate, cement, water, fly ash and superplasticizer. Fly ash will remove the cement by 10%, 20%, 30%, 40% and 50%. The removal of cement by fly ash will result in an economic structure and it will reduce the CO2 emissions which will result as a sustainable environment, whereas the superplasticizer will be added as 0.7% and 0.8%. The samples were kept for curing to enhance the strength of concrete was at room temperature.
