Foundry sand is a byproduct of ferrous and non ferrous metal casting industries. Because of its thermal conductivity sand has been used as a molding material. In metal foundries the metal is used for casting purpose. The sand used for foundries will be recycled and reused. The waste sand which is not reused will be removed from foundry. Here we will study about the applications of foundry sand in civil engineering disciplines which is environmentally safe. By this the problem of disposal of foundry sand is solved. Foundry sand consists of silica sand, coated with a thin film of burnt carbon, residual binder and dust. Foundry sand can be used as partial replacement of fine aggregates or total replacement of fine aggregate. The percentages of replacements were 10, 20 and 30% by weight of fine aggregate. Here we investigated about the effects of foundry sand on properties of concrete in terms of compressive strength, split tensile strength and modulus of elasticity. Tests were performed at different curing periods i.e. 7, 14, 28 and 56 days respectively. Test results showed that there is an increase of compressive strength, split tensile strength and modulus of elasticity. So the use of foundry sand is safe in concrete for strength and durability purpose
