To evaluate the effect of dry sludge on concrete performance, its physical and mechanical properties were studied. In this research an attempt is taken to bring into play the sludge waste in various proportions so that the final product property of concrete mixture is same as the control mix. Waste sludge material was replace with fine and coarse aggregate in various percentages such as 50%, 45%, 40% ,35%,30%, 25%,20%,15%, 10%, 5%, 4% and 3%. Reference concrete mix is also made for comparative reasons.
