Abstract
The growing volume of industrial waste is a worrying reality that has given rise to problems with environmental sustainability and earth surface ecology. By emitting carbon dioxide and other damaging chemicals into the atmosphere while being manufactured, fibre production contributes to global warming. Additionally, it processes waste generated during production and field use. Therefore, using industrial waste in the composition of concrete can aid in reducing ecological and environmental issues. In this investigation, fibre (waste polypropylene fibre) was added to cement concrete as an additional material. A synthetic hydrocarbon polymer called polypropylene fibre (PPF) used as partial replacement of fine aggregate was added to the concrete to increase its compressive and split tensile strength. In this investigation, we created a variety of specimens using different amounts of polypropylene waste, including (0%, 0.25%, 0.5%, 0.75%, and 1.00%). The compressive strength and split tensile strength of the fiber-reinforced concrete (FRC) were measured after 7 and 28 days of curing, whereas the density of the FRC was assessed right away after the preparation of the concrete mix. According to the results, adding polypropylene fibre causes the density of new fiber-reinforced concrete (FRC) to slightly or barely decrease from 2397 kgcm3 to 2393 kgcm3. For all curing ages up to a specific point, adding discarded polypropylene fibre increases the strength of fibre reinforced concrete (FRC). The strength of the Fibre Reinforced Concrete (FRC) suddenly decreases after that. For maximal strength with a low coefficient of brittleness, 0.5% polypropylene fibre addition is advised. The Fibre Reinforced Concrete (FRC)'s compressive strength increases by 10% and its split tensile strength by 17% with the addition of 0.5% waste polypropylene fibre. In our research we prepared different concrete mixes with partial replacement of cement with variable percentage of Rice Husk Ash i.e. 0%, 2.5%, 5%, 7.5% and 10% and we tested these mixes for compressive strength at 7 days, 21 days and 28 days. Waste kadappa stones were partially replaced as coarse aggregates in 20%, 40% and 60% respectively are casted and tested for compressive strength at 7 and 28 days.
