STRENGTH BEHAVIOUR OF FOUNDRY SAND ON MODIFIED HIGH STRENGTH CONCRETE

Jayachandra, Shashi kumar.A, Sanjith.J, DG.Narayana

Abstract: Metal foundries use a large amount of sand as part of the metal casting process. Foundry industries generally recycle and reuse the used foundry sand many times in casting process. When the sand can no longer be reused in the foundry, it is removed from the foundry and is termed as foundry waste sand. Like many waste products, foundry sand has beneficial applications to other industries. A mixture of silica sand coated with a thin film of burnt carbon and residual binder with traces of dust is termed as foundry sand. From the previous available literature it was found that replacement of sand by foundry sand by certain initial percentages gives a marginal increase in hardened properties of normal strength concrete. In the present work, fine aggregate is replaced by foundry sand with percentages and tests were performed for hardened properties of modified high strength concrete for all replacement levels.
