Jul 22, 2015· Concrete disposal is difficult and even dangerous because it is heavy and unwieldy. Even transporting concrete debris can be a challenge. Unlike other construction waste materials, or C&D waste, concrete has both additional considerations for hauling and disposal, but it also provides additional opportunities for recycling.

production of concrete will also induce a relief on waste disposal issues. Now-a-days the cost of material is increasing so if we use the waste material in the production of the concrete so we decrease the price. In India, million tons of wastes from marble industries are being released from marble cutting, polishing, processing and grinding.
