Experimental Investigation on the Enhancement of Compressive Strength of 5% Novel Polypropylene Monofilament Fiber as Additive in Concrete with Conventional Concrete

Avula Siva Rami Reddy and Paul Manoharan Priya Rachel

Abstract

The aim of this study is to investigate the enhancement of the compressive strength of concrete using 5% novel polypropylene monofilament fiber as additive in concrete with conventional concrete. Cement was partially replaced with polypropylene monofilament to increase the concrete’s compressive strength. The experiments were divided into two groups. Each group consists of 18 specimens. Pretest power is calculated at 80%. 5% of polypropylene monofilament was replaced in concrete by the weight of cement. A compressive strength test was carried out per ASTM standards using a cube specimen on dimensions 150 x 150 x 150 mm. After 28 days at room temperature, the compression strength of the specimens was measured using a compression testing machine of 2000 kN capacity. SPSS (Statistical Package for the Social Sciences) Software was used to carry out independent sample t-tests. Novel polypropylene monofilament fiber-reinforced concrete exhibited a compressive strength of 37.6489 N/mm2 compared to conventional concrete. The standard deviation for novel polypropylene monofilament fiber-reinforced concrete for 5% replacement with concrete was 2.30843. A statistically significant difference between the two study groups, with a significance value of p = 0.000 (two-tailed, p < 0.05) was observed. The compressive strength of concrete significantly increased with the replacement of 5% novel polypropylene monofilament fiber- reinforced concrete in cement.
