HYPO SLUDGE AS A PARTIAL REPLACEMENT OF CEMENT IN CONCRETE by Navraj Kaur Brar
The increasing amount of waste is a concerning reality that has arose the sustainability issues of the environment. Hypo sludge in the paper mill generates a huge amount of waste in the form of slurry, disposal of which causes environmental pollution. The production of cement also accounts for the global warming by releasing carbon dioxide (CO₂) into the atmosphere. Therefore, formulation of concrete with industrial waste can help in minimizing the environmental problems. In this study hypo sludge was used as a replacement of cement in concrete. In present experimental investigation, the various percentages of hypo sludge such as 10%, 20%, 30% and 40% were replaced by cement in concrete. The different parameters with varying proportions of hypo sludge to minimize the use of cement in concrete such as the compressive strength at 7 days and 28 days, flexural strength, split tensile strength and water permeability test at 28 days.
