PERFORMANCE OF PERVIOUS CONCRETE MADE WITH BLACK MARBLE STONE AGGREGATE

Civil Engineering

Normal or conventional concrete, which is a combination of cement, sand, coarse aggregate and water, forms a hard surface. The fast urbanization and infrastructure developments cause compactly constructed buildings. Depletion of ground water is a major problem today due to the lack of percolation of rain water into the soil. The impermeable nature of conventional concrete restricts the flow of rainwater into the ground. Pervious concrete is one solution to this problem. Pervious concrete is also called enhanced porosity concrete, which is used widely nowadays due to its higher infiltrating ability. Pervious concrete is made up of cement paste, coarse aggregate with little or no fine aggregate. The paste binds the aggregate particles together to develop a system of interconnected and highly permeable voids that encourage the quick drainage of water. Generally, it is used in parking areas, areas with light traffic, residential streets, pedestrian roads and drain covers. The proper utilization of pervious concrete is recognized as Best Management Practice by the U.S. Environmental Protection Agency (EPA) for providing storm water management.
