This paper presents the salient features of an experimental study on concrete using S.C.B. Powder. Concrete blocks prepared by partially replacing cement with S.C.B. powder are tested for the compressive strength, water absorption capacity and density characteristics with varying replacement percentage of cement with S.C.B. powder. Honey- combing remain in concrete during concreting work is the major concern to the civil engineer, structural engineers. The effect on the formation of honey combing is critically examined by casting concrete block using SCBP. S.C.B. powder, the waste obtained from steel factories, M.S. steel workshops if used for partially replacing cement can influence compressive strength of concrete to a considerable extent. Keeping this in view an experimental study has been carried out to test the performance of S.C.B. powder in cement concrete blocks. Effect of type of curing on compressive strength, density etc. have also been carried out on various proportions of cement and S.C.B. powder partially replaced with varying % of cement by weight. Blocks of 150* 150* 150 mm are considered for test report. The results of the various tests are sufficiently encouraging and author suggests to use up to 6% S.C.B. powder. Since compressive strength for this ratio is found to be 20.14 N/MM2 under gunny bag curing condition and provides optimum & desired result for M15 grade of concrete. Other parameters are also found improved.
