A Study On Properties And Use Of Environmental Friendly Pervious Concrete

Pervious concrete is an open graded material specially engineered to have high porosity to allow water from precipitation and other sources to pass through besides of retaining sufficient strength allowing its use to perform various structural functions. Due to larger porosity in the pervious concrete mass, its strength is lower when compared with conventional concrete, even; pervious concrete of sufficient strength has been prepared using different combinations of ingredients so that it can find enough application areas. Recently it is predominantly being used for pavement applications in light traffic density areas like parking lots, side walks, service lanes etc. Now-a-days our modernized cities are covered with air-water proof building material. It obstructs the lack of air permeability and water permeability common concrete pavement so that the rain water is not filtered underground. A large amount of rain water ends up falling on impervious surface such as parking lots, drive ways, sidewalks and streets rather than soaking into soil. This creates a natural imbalance in the ecosystem and leads to various problems like soil erosion, floods, ground water depletion. A simple solution is to be avoiding these problems to stop construction impervious surface and switch to pervious concrete. Working on rain-drain concept, porous concrete allows large amount of water in the body system resulted ground water rechargement and control storm water management. Pervious concrete pavement is the best solution for protecting trees in a impervious surface. Many plants have faced difficulty growing in impervious because air and water can’t touch to the roots. Porous concrete helps the adjacent trees to receive more water and air from the soil
