REINFORCEX: EXPLORING MECHANICAL BEHAVIOR OF FIBERREINFORCED CONCRETE FOR HIGH-PERFORMANCE STRUCTURES

Abstract

Fiber-Reinforced Concrete (FRC) has emerged as an advanced construction material capable of enhancing the mechanical performance and durability of conventional concrete. The incorporation of discrete fibers improves tensile strength, crack resistance, ductility, and energy absorption capacity. This study investigates the mechanical behavior of fiber-reinforced concrete designed for high-performance structural applications. Steel and polypropylene fibers were incorporated in varying volume fractions to evaluate their influence on compressive, split tensile, and flexural strength. Experimental analysis was conducted through standard mechanical testing procedures. The results indicate significant improvement in tensile and flexural strength with increasing fiber content. Crack propagation was effectively controlled due to fiber bridging mechanisms. The study demonstrates that FRC exhibits enhanced postcracking behavior and improved structural integrity. The findings confirm its suitability for high-load and seismic-prone structures. The research contributes to understanding optimized fiber dosage for performance enhancement.
