Utilization of Demolished Concrete and Construction Waste as Coarse Aggregate in Concrete

In the construction field of the world, use of construction & demolished waste as alternative of coarse aggregate plays an vital role to save natural resources and economically good for us. In present days for human, environmental issue is very important thus it seeks to improve construction & demolished waste material for construction. The use of construction and demolition waste is giving a prospective application in construction and gave an alternative to natural coarse aggregate. In the laboratory the construction & demolished waste has been tried as replacement substitute to natural coarse aggregate in concrete making of cubes, beams. These were cast and tested for compressive strength and flexural strength after a curing period of 7, 14, 28 days. The results indicate effectiveness of construction & demolished waste as partial replacement of natural coarse aggregate up to 15 percent, without affecting the design strength.
