GAINFUL UTILIZATION OF HYPO SLUDGE IN CONCRETE

To mitigate emission of carbon dioxide and other green gases, it is necessary to develop alternative ways by which sustainable development can be improved. This paper discusses various combination of cement with hypo sludge and different size of aggregates. Hypo sludge has a very good content of Cao and thus it works as a partial replacement material in construction process. This study examines 5%, 10%, and 15% replacement of hypo sludge in place of cement in concrete for M20 and then tested for its compressive strength. The result shows that the strength of the concrete increases by adding hypo sludge up to 10%. However, further increase in hypo sludge decreases the compressive strength. Also, rate analysis has been done which concludes that the rate of the concrete decreases on replacing the cement with hypo sludge. The aim of this study is to make eco-friendly building material and to see how the concrete behaves on replacing the cement with the hypo sludge in various proportions. This study also examines the possibility of utilization of hypo sludge as a partial replacement material and it can be further used as cementitious material. It also helps with the disposal and pollution problems associated with paper industry waste.
