Abstract: The increasing amount of waste is a concerning reality that has arose the sustainability issues of the environment. Hypo plant in the paper industry generates a large volume 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 in 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. Polypropylene fiber (PPF) is a synthetic hydrocarbon polymer which was addedto augment the strength of the concrete. In present study, 450 specimens were prepared by varying percentage of hypo sludge (0%, 5%, 10%, 15% & 20%) and polypropylene fiber (0%, 0.25%, 0.5%, 0.75%&0.10%). The workability of concrete was tested immediately after preparing the concrete whereas the compressive strength and the splitting tensile strength of concrete tests were tested after 7,14 and 28 days of curing. Results indicate that the workability of concrete decreases from medium to low with an increase in content of hypo sludge and polypropylene fiber. The addition of both hypo sludge and polypropylene fiber increases the strength of concrete for all curing ages up to certain point. After that, there is an abrupt reduction in strength of the concrete. The combination of 10% hypo sludge and 0.5% polypropylene fiber is recommended for the maximum strength with minimum coefficient of brittleness. Incorporation of hypo sludge decreases the cost of concrete upto 18.35%.
