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 solid waste.Paper fibers can be recycled only a limited number of times before they become too short or weak to make high qualitypaper. It means that the broken, low-quality paper fibers are separated out to become waste sludge. All the inks, dyes,coatings, pigments, staples and "stickiest" (tape, plastic films, etc.) are also washed off the recycled fibers to join thewaste solids. The shiny finish on glossy magazine-type paper is produced using a fine kaolin clay coating, which alsobecomes solid waste during recycling. This paper mill sludge consumes a large percentage of local landfill space foreach and every year. Worse yet, some of the wastes are land spread on cropland as a disposal technique, raisingconcerns about trace contaminants building up in soil or running off into area lakes and streams. Some companies burntheir sludge in incinerators, contributing to our serious air pollution problems. To reduce disposal and pollutionproblems emanating from these industrial wastes, it is most essential to develop profitable building materials from them.Keeping this in view, investigations were undertaken to produce low cast concrete by blending various ratios of cementwith hypo sludge.This research work describes the feasibility of using the Hypo Sludge in concrete production asreplacement of cement by weight. The use of Hypo Sludge in concrete formulations as a supplementary cementationsmaterial was tested as an alternative to conventional concrete. The mix has been replaced by Hypo Sludge accordinglyin the range of 0% (without Hypo Sludge), 10%, 20%, 30% and 40% by weight of cement for M-40 mix.
