| In this paper , a thirsty concrete used for roadway is introduced .It is an concrete with high porosity used for flatwork applications that allows to pass through which reduces the runoff from a site and help recharging ground water levels. Using the common material and method, the strength of the pervious concrete is low. Hence the materials with different type, shapes and sizes are used to get better results. The infiltration rate, abrasion resistance and durability of the materials used are also good. And an experimental study evaluating strength and permeability characteristics of a pervious concrete mix design is presented. The experimental work included compressive strength tests(at 7 and 28 days, and infiltration rate test(at 28 days) on clean specimens .Resulting that Its void content ranges from 18 to 35% with compressive strengths of 2.74 to 27.56 MPa .Pervious concrete is used in parking areas, roadways, pedestrian walkways, and greenhouses and contributes to sustainable construction. In this project scrap marble is used to make pervious concrete and also checking various parameters like permeability and compressive strength with respect to different shapes of aggregate like angular, rounded, and flaky type. Under the guidance of J. Kumar RMC plant PUNE, this project was successfully completed. |
