Abstracts: There is a need to identify suitable alternative material from industrial waste in place of river sand. The utilization of quarry dust which is a waste material has been accepted as building material in many countries for the past three decades. The effect of w/c ratio on hardened properties of ordinary concrete with partial replacement of natural sand by manufactured sand is investigated. Designed Concrete mix with w/c ratio of 0.5 of grade M-25 is used in experimental study. Concrete cube specimens are tested for evaluation of compressive strength. The concrete exhibits excellent strength with replacement of natural sand by manufactured sand. This project will help to find viable solution to the declining availability of natural sand to make eco-balance.
