Concrete has been in use since time immemorial. There are evidence that the earliest civilizations of this planet used concrete for
its utility in different purpose and ways. It is a composite material composed mainly of water, aggregates and cement. Now a days
concrete is playing vital role in highway constructions as rigid pavement. As there is increase in highway developmental
activities, it leads to higher demand of sand, which can be fulfilled by sand mining from surface water bodies. Due to disastrous
environmental consequences, extraction of sand from surface water bodies is restricted to some extent. This leads to scarcity of
sand, to overcome this manufactured sand (M sand) can be used as partial replacement of natural sand. Aim of present study is to
find optimum content of M sand in M25 grade concrete as partial replacement of natural sand from 0% up to 45% with 15%
variation. To find the optimum content of M sand the mechanical strength parameters viz., compressive strength and flexural
strength tests were conducted
