Compressive Performance of Concrete using Hypo Sludge and Polypropylene Fiber

Today’s fast-growing industrialization where production of materials is touching the remarkably Heights, so it’s the need of an hour to utilize the waste which is produced in these factories. Paper producing industries generates a huge quantity of waste, it overcome these problems we need to tackle with alternate methods which will help to the reduce the impact of major environmental problems. This factory ash is known as Hypo Sludge Ash (HSA), for the assembly of paper the chemical is mixed and used for a numerous time for producing the paper of good quality but once its usefulness is achieved the staple can’t be again utilize and also Ground Granulated furnace slag which is that the by-product of ore is used for comparison and its usefulness is suggested. In this project work these wastes is used to replace the cement in various proportions and noticeable changes in reading are recorded. Accordingly, the design mix is made for M40 grade concrete and testing is performed by means of compression testing machine (CTM) and flexural testing machine. It was found that optimum results are obtained at 10 % a replacement of factory ash. 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 added to 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 sure 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 suggested for the utmost strength with minimum coefficient of brittleness. Incorporation of hypo sludge decreases the cost of concrete up to 18.35%.
