摘要：Hypo Sludge is a waste produced in the paper manufacturing industry. Paper mills generate more than 4million tons of sludge each year for disposal. Hypo Sludge is known to contain useful fibers and chemicals, as myproject to get good results by adding of ferrous oxide to the hypo sludge to the fly ash improve the strength, durability,and life span of concrete structures exposed to weather. Paper making generally produces a large amount of solidwaste. Paper fibers can be recycled only a limited number of times before they become too short or weak to make highquality paper. It means that the broken, low-quality paper fibers are separated out to become waste sludge. Thisresearch work describes the feasibility of using the Hypo Sludge in concrete production as replacement of cement byweight. The use of Hypo Sludge in concrete formulations as a supplementary cementations material was tested as analternative to conventional concrete. The mix has been replaced by Hypo Sludge accordingly in the range of 0%(without Hypo Sludge), 10%, 20%, 30% and 40% by weight of cement for M-40 mix.Concrete mixtures wereproduced, tested and compared in terms of compressive strength for 28 days.
