Effect of Novel Polypropylene Fiber and Natural Fiber Based Concrete Compared to Conventional Concrete with Respect to Flexural Strength

This study’s primary goal is to increase the strength of plain cement concrete. An effort has been made to research the impact of extra polypropylene fiber in regular Portland cement concrete in an effort to enhance these features of plain concrete. In this experimental investigation, flexural strength tests and flexural strength tests at 28 days for concrete of the M25 grade were conducted to determine the effects of fibers in various percentages (between 3 and 4%). The flexural beam size was taken as 500 mm x 100 mm x 100 mm. According to test re-sults, concrete with polypropylene fiber demonstrates superior performance than concrete without fiber. Comparison of both polymers reinforced concrete beam and conventional concrete beam mean value is (13.0372, 14.4730, and 16.0122), standard deviation is (0.20096, 0.29784), and the standard error is (0.04737, 0.07020). The SPSS (Statistical Package for the Social Sciences) carried out has a significance of 0.000 (p < 0.05). This shows that there is a statistically significant difference between the two groups considered in this study. Fiber insertion much more improves the flexural strength of concrete.
