While the density of the fiber-reinforced concrete (FRC) is determined right away after the concrete mix has been prepared, the compressive strength and split tensile strength of the FRC are tested 7 and 28 days after it has been cured. As a result of adding polypropylene fibre, new fiber-reinforced concrete (FRC) has a marginally or barely decreased density from 2397 kg/m3 to 2393 kg/m3, according to the results in laboratory. Waste polypropylene fibre boosts the strength of fibre reinforced concrete for all curing ages up to a particular degree (FRC). After that, there is a rapid decline in the strength of the fiber-reinforced concrete (FRC). It is recommended to add 0.5% of polypropylene fibre for maximum strength and minimal brittleness. The inclusion of 0.5% waste polypropylene fibre raises the split tensile strength and compressive strength of the fiber-reinforced concrete by 16.9908% and 9.988470%, respectively (FRC). |
