An Experimental Study on Economic Feasibility and Strength of Concrete by Partial Replacement of Cement with Hypo Sludge

Mahesh Shirur | Yashwanth M. K

Abstract: To produce low cost concrete by blending various ratios of cement with hypo sludge and to reduce disposal and pollution problems due to hypo sludge it is most essential to develop profitable building materials from hypo sludge. The innovative use of hypo sludge in concrete formulations as a supplementary cementitious material was tested as an alternative to normal concrete. In this study, hypo sludge is physically and chemically characterized and partially replaced in the ratio of 0 %, 10 %, 20 %, 30 %, 40 %, 50 %, 60 % and 70 % by weight of cement, natural River sand as fine aggregate and normal coarse aggregate were used to produce concrete. Mix design of concrete is done as per bureau of Indian standards; the fresh properties of concrete like slump test and compaction factor test and hardened properties like compressive strength and split tensile strength were carried out. The test results indicated that fresh and hardened properties of the concrete increases as the percentage of replacement of hypo sludge increases up to 30 % and economic feasibility of hypo sludge based concrete is less compared to conventional concrete.
