摘要：The increasing amount of wastes is a concerning reality that has arose the sustainability issues forthe environment. Large amount of wastes such as fly ash (from thermal plant), hypo sludge (frompaper mill industry) etc. is generated annually which are generally disposed off by landfills leading toenvironmental pollution. Hypo plant in the paper industry generates large volume of waste in the formof a slurry. This solid waste directly affects the soil properties and contributes to the soil pollution.Also, the production of cement accounts for the global warming by releasing carbon dioxide in theatmosphere. Therefore, the formulation of concrete with industrial waste can help in minimizing theenvironmental problem. In this study, hypo sludge was used as a replacement of cement in concrete.Polypropylene fibre (PPF) was added to strengthen the concrete. In this research work 25 mixes wereprepared at different replacement levels of hypo sludge (0%, 5%, 10%, 15%, 20%) and polypropylenefibre (0%, 0.25%, 0.5%, 0.75%, 0.10%) for M-20 mix. Workability was determined; the compressivestrength and splitting tensile strength of concrete were tested after 7, 14 and 28 days of curing.
