Abstract: This investigation is focused on the evaluation of strength of concrete specimen in which ordinary Portland cement is partially replaced by hypo sludge and fine aggregate by manufactured sand. In addition to that the specimens were also tested for fire resistance. In this investigation cement is replaced by 20 percent of hypo sludge and fine aggregate by manufactured sand at 75 percent replacement. The tests were carried out to evaluate the mechanical properties like compressive strength and split tensile strength at 7 days and 28 days for the concrete mix M35 in which cement replaced by hypo sludge via 5%, 10%, 15%, and 20% and at the same time for the concrete mix M35 in which cement is replaced by hypo sludge via 5%, 10%, 15% and 20% and fine aggregate by manufactured sand via 15%, 30%, 45%, 60% and 75%.

Keywords: Hypo waste, compressive and split tensile test and elevated temperatures, m35 grade, manufactured sand
