【 摘 要 】
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. Pervious concrete creates opportunity for lands caper and architects who wish to use greenery in parking lots and paved urban areas. Inspired by the pervious concrete technology and the fact that fly ash is a waste material abundantly available, the research Group at KIIT University, India commenced a comprehensive research programme on fabrication of Fly ash based pervious Material [FPC] from fly ash. The compressive strength of the material falls on the range of 3-28 MPa, porosity 15 - 35 % with permeability 8 - 20 mm/s. This material has potential application such as ground water rechargement, storm water management, noise reduction, control surface run-off, temperature behaviour and pollution retention sinks. The research mainly focuses on the manufacture of fly ash-based pervious material for ground water rechargement and large amount of utilization fly ash.
