Enhancing Mechanical Properties of Concrete by Adding Polypropylene Fibers
Utilized extensively in construction, concrete stands out for its remarkable compressive strength and continuous nature. Nevertheless, the susceptibility to cracking under pressure presents structural challenges, compromising overall continuity. To tackle this concern, the integration of synthetic filaments, notably Polypropylene filaments (PP), emerges as a promising solution. Within this investigation, an exhaustive experimental study was undertaken to explore the influence of varying lengths and proportions of PP filaments on concrete specimens. Three distinct mixes of Fiber-Reinforced Concrete (FRC-1, FRC-2, and FRC-3) were formulated, incorporating different ratios of 6 mm and 12 mm fibers, alongside a plain concrete (PC) mixture for comparative analysis. The specimens underwent a series of tests, including assessments for contraction, flexural strength, splitting tensile strength, and pure shear strength, aiming to evaluate their mechanical properties. The results from the pure shear strength test highlighted the effectiveness of PP fibers in enhancing concrete's resistance to shear loads. FRC-1 and FRC-2 demonstrated superior performance compared to other samples, with FRC-2 exhibiting a noteworthy 11% augmentation in pure shear strength when compared to plain concrete.
