Experimental Studies in the Flexural Performances of Novel Polypropylene Monofilament Fibers as Additives in Concrete with Conventional Concrete

Abstract

The research investigates the flexural performance of novel polypropylene monofilament fiber as additive in concrete with conventional concrete. Some of the cement was replaced with novel polypropylene monofilament to strengthen the concrete’s flexural properties. The experiments were divided into two groups. Each group includes 18 different specimens. Pretest power is calculated at 80%. In concrete, cement weight replaced 8% of the polypropylene monofilament. A 100 x 100 x 500 mm prism specimen was subjected to an ASTM standard flexural strength test. The specimens were allowed to cure for 28 days at room temperature before being tested for tensile strength. The independent sample t-test was carried out using SPSS (Statistical Package for the Social Sciences) software version 21. The mean flexural strength of polypropylene monofilament novel fiber-reinforced concrete, with an 8% replacement, was 14.9611 N/mm 2 , as compared to conventional concrete’s 12.9111 N/mm 2 . An independent sample t-test was used to analyze the results. The novel polypropylene monofilament fiber-reinforced concrete had an 8% standard deviation that was 0.360. A significance value of p = 0.000 (two-tailed, p < 0.05) with a statistically significant difference between the two study groups, was noted. When polypropylene mono-filament novel fiber-reinforced concrete is used in place of conventional concrete, the strength of the concrete’s flexural component significantly increases.
