Flexural Strength of Porous Concrete Using Building Demolished Waste
Researches, designers and builders are always looking for new and improved ways to protect the environment during development in the most effective ways possible.one emerging technology is the use of porous materials such as pervious concrete as an alternative material for surfaces in low traffic areas. Pervious concrete is a concrete containing building demolished waste, coarse aggregate and cement paste. It seems pervious concrete would be a natural choice for use in structural applications in this age of Ã¢â‚¬Ëœgreen buildingÃ¢â‚¬â„¢. It consumes less raw material than normal concrete, it provides superior insulation values when used in walls, and through the direct drainage of rainwater, it helps recharge groundwater in pavement applications. Pervious concrete is one of the leading materials used by the concrete industry as GREEN industry practices for providing pollution control, storm water management and sustainable design. The increased interest in pervious concrete is due to those benefits in stormwater management sustainable development. The flexural strength properties of the concrete have been investigated for nominal mix and mix design as per the mix design codes IS 12727:1989 and IS 10262:2009. Various proportions of cement, water and percentage of coarse aggregates and building demolished wastes are used. In this paper 40:60, 50:50 and 60:40 ratio of coarse aggregate and building demolished wastes are used with water cement ratio 0.4 to 0.48.
