EXPERIMENTAL STUDY ON STRENGTH OF CONCRETE BY USING HYPO SLUDGE, FLY-ASH & IRON OXIDE

The worldwide concrete industry contributes around 9% of ozone depleting substance emanation to the world's environment and Industrial Wastes are being delivered by 420 million tons for each annum by compound process in India. To diminish concrete assembling and transfer issue of paper squander, there is a need to create elective fasteners in development field. Use of mechanical waste items as Supplementary Cementitious Material (SCM) in concrete is imperative perspective in perspective of conservative, natural and specialized reasons. In this Research, The mix has been replaced by Hypo Sludge accordingly in the range of 0% (without Hypo Sludge, fly ash, ferrous oxide), 10%, 20%, 30% and 40% by weight of cement for M-20 mix. Concrete mixtures were produced, tested and compared in terms of compressive strength, durability& life span to the conventional concrete. These tests were carried out to evaluate the mechanical properties. For the test results for compressive strength up to 56 days are taken. In the test performed, the optimum compressive stress obtained by utilizing paper waste was at 30% replacement. At the place where strength is not of more importance or rather structure is for temporary basis then design mix proportion up to 40% replacement can also be utilized. Test also point towards developing low cost concrete by varying design mix proportion from 10%replacement to 40%replacement. The compared values of cost show gradual decrement in total cost of per cubic meter concrete.
