Abstract

This experimental study evaluates the influence of incorporating steel and polypropylene fibers on the mechanical performance of high- performance concrete (HPC) across M30, M35, and M40 grades. This research focuses on evaluating the mechanical properties of High- Performance Concrete (HPC) enhanced with a hybrid reinforcement system consisting of steel fibers (SF) and polypropylene fibers (PPF). Steel fibers are utilized to improve the compressive and tensile strengths, while polypropylene fibers contribute to enhanced crack control and energy dissipation. Various HPC mixtures with different volume ratios of SF and PPF were designed and subjected to experimental testing, including compressive strength, tensile strength, flexural performance, and damping behavior. The findings indicate that the incorporation of hybrid fibers notably increases the ductility, crack resistance, and deformation capacity of HPC in comparison to conventional concrete. The optimal fiber combination achieved a balanced improvement in structural performance while maintaining acceptable workability. This study underscores the synergistic effect of steel and polypropylene fibers in advancing the mechanical performance of HPC, making it suitable for applications requiring high durability and seismic resistance. Among the various combinations studied, an optimal proportion of steel and polypropylene fibers provided a balanced enhancement of mechanical properties without adversely affecting workability. The synergistic interaction between steel and polypropylene fibers was found to be more effective than the use of individual fibers alone. Overall, this study highlights the potential of hybrid fiber-reinforced HPC for structural applications requiring superior strength, durability, and seismic resistance, particularly in infrastructures subjected to dynamic and impact loads.
