摘要：Concrete plays a vital role as a construction material in the world. In the present scenario, wastematerials from various industries are added to the mix. Over 400 million tons of waste materials are being produced byvarious industries every year. Metal industries use large amounts of sand as part of the metal casting process. Foundriessuccessfully recycle and reuse the sand many times in a foundry. When the sand can no longer be reused in thefoundry, it is removed from the foundry and is termed as Foundry sand. Foundry sand production is nearly 6 to 10million tons annualy. There is a possibility of substituting natural fine aggregate withwaste foundry sand which offerstechnical, economic and environmental advantages which are of great use in the construction sector. The constructionindustry is now slowly becoming aware of the environmental issues and other sustainable development issues forcement and concrete industries. It is looking for the ways and means to develop building products, which will increasethe life span and quality.
