The effect of water cement ratio on fresh and hardened properties of concrete with partial replacement of natural sand by manufactured sand and foundry sand was investigated. Concrete mix design of M30 (4350 psi) grade was done according to Indian Standard code (IS: 10262). Concrete cube specimens were tested for evaluation of compressive strength. Workability was measured in terms of slump, compacting factor and vee bee consistometer. The concrete exhibits excellent manufactured strength with 25% replacement of natural sand and for foundry sand strength with 25% replacement of natural sand by using the deep curing method so it can be used in concrete as viable alternative to natural sand. This paper puts forward the applications of manufactured sand and foundry sand as an attempt towards sustainable development in India. It will help to find viable solution to the declining availability of natural sand to make eco-balance.
