Studies on Infiltration Rate of Pervious Concrete
Concrete is the only material in the construction engineering for which the usage has been multifold over the last decade. Owing to rapid urbanization, there has been an increase in the consumption of construction materials by which the natural resources are depleting day by day. Porous concrete or no fines concrete or permeable concrete is known as special type of concrete which allows the water to penetrate through the concrete, thereby reducing the external runoff and boosting the ground water table. As pervious concrete has little to no fine aggregate, the voids of coarse aggregate particles will be filled by the cementitious paste to preserve the interconnectivity. The perviousness is the only parameter which indicates the penetrability of no fines concrete. Since the rate of infiltration depends upon pore sizes, geometry and interconnectivity of coarse aggregate, it exactly indicates the effectiveness of pervious concrete. To preserve the water quality for future generations, the pervious concrete can be used as sustainable construction practice. In the current study, the experiments were carried out with a constant water/cement, varying cement/aggregate and also varying size of aggregate in the total aggregate content. The compressive strength was determined for standard cubes of 150 × 150 mm. The falling head permeability apparatus was designed to determine the coefficient of permeability for various samples. The cylinder-shaped casts of 11 cm in diameter and 18 cm in depth were used to determine the rate of infiltration by conducting permeability test on pervious concrete. The mix proportion satisfying infiltration rate and strength properties is recommended as the sustainable pervious concrete.
