A Study on Compressive Strength of Self- Compacting Concrete Using Portland Slag Cement with Partial Replacement of Fine Aggregate by Foundry Sand

S RamaKrishna Raju, RD Venkatesh, S Adiseshu

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