Effective use of Paper Sludge (Hypo Sludge) in Concrete
Santosh Ahirwar,  Dr. Rajeev Chandak
More than 300 million tonnes of industrial waste are produced per annum in India mainly by chemical and industrial waste. Hypo sludge is a type of waste obtained by paper production industries.Disposal of this waste become huge difficult. It means that the broken, low quality paper fibers are separated out to become waste sludge. This paper mill sludge consumes a large percentage of local landfill space for each and every year. To reduce disposal and pollution problems emanating from these industrial wastes, it is most essential to develop profitable building materials from them. Keeping this in view, large quantity of national and international references are studied and based on these the state of art of the research and investigations on the production of low cost concrete by blending various ratios of cement with hypo sludge is presented in this paper. Concrete specimens were prepared with 7.5%, 10%, 12.5% and 15% hypo sludge as a replacement of cement weight, The most important mechanical property of concrete is compressive strength and it is evaluated on 150X150X150 mm cubes by The compressive strength is obtained for 28 day strength and results are analyses.
Keywords- hypo sludge, Ordinary Portland cement (O.P.C.), Compressive strength.
