Abstract
Hypo sludge in the paper industry creates a significant amount of trash in the form of slurry, and its disposal pollutes the environment. The production of cement releases carbon dioxide into the atmosphere, which furthers the problem of global warming. The growing amount of trash is a worrying fact that has brought up environmental sustainability concerns. As a result, making concrete from industrial waste might help to ease environmental problems. Hypo sludge was used in this experiment to make concrete for CC Pavements in place of cement. A synthetic hydrocarbon polymer called polypropylene fibre (PPF) was added to the concrete to increase its strength. The percentages of hypo sludge (0%, 5%, 10%, 15%, and 20%) and polypropylene fibre (0%, 0.25%, 0.5%, 0.75%, and 0.10%) varied in the current research. While the workability of concrete was examined immediately after the preparation of the concrete, the compressive strength and split tensile strength of concrete samples were measured 7, 14, and 28 days after curing. For all curing ages and to a certain extent, the introduction of hypo sludge and polypropylene fibre increases the strength of concrete. After then, the concrete's strength dramatically decreases. For optimal strength with a low coefficient of brittleness, a mixture of 10% hypo sludge and 0.5% polypropylene fibre is advised.
