An Experimental Study on the Mortar Using Waste Foundry Sand as Fine Aggregate

Problem of the environmental pollution and pollution by vast quantity occurrence of industrial waste by progress of industry is risen recently. Is real condition that waste foundry sand to be industrial waste that happen in casting industry of them has much the occurrence amount and the processing method is depending on most simplicity reclamation and so on. Therefore, by using waste foundry sand in the world by fine aggregate for mortar in recycling side of industrial waste necessity of development for new principal parts aggregate is risen along with rise of aggregate price by exhaustion phenomenon of natrual resources, wish to analyze physical and mechanical properties special quality and foretell practical use possibility availability.
