Abstract: Pervious concrete is a special type of concrete with a mixture of cementatious material, the coarse aggregate of smaller size, admixtures, and water. Pervious concrete applications include road pavements, rainwater harvesting -and drainage in retaining walls due to its high porosity. The void content and water-cement ratio of pervious concrete are in the range of 15-30% and 0.27-0.36, respectively. The experimental data is collected from the literature cover and graphs are drawn for water to cement ratio, cement to aggregate ratio versus compressive strength. The maximum size of aggregate used in the mixture of pervious concrete is 20mm, thus, influences the porosity range from 11%-60%. In this paper, regression equation is predicted and validated for strength parameters like compressive strength, porosity, density of pervious concrete and the experimental results are obtained from the experiment done for the beams of size 500*100*100mm dimensions by using Master Glenium as the admixture in pervious concrete and the graphs are drawn for the predicted versus experimental results.
