        abstract = {This study presents an experimental investigation on the strength and durability characteristics of Fiber-Reinforced High-Performance Concrete (FRHPC) incorporating steel and polypropylene fibers. High Performance Concrete (HPC) is known for its superior strength, durability, and low permeability; however, its brittleness and crack-prone nature under tensile and flexural stresses necessitate further enhancement. To address this, six concrete mixes were designed with varying fiber contents: a control mix (M0), individual fiber mixes, and hybrid fiber combinations. Ground Granulated Blast Furnace Slag (GGBFS) was used as a partial replacement for cement to improve durability and sustainability, while a polycarboxylate-based superplasticizer ensured required workability. The performance of each mix was evaluated through a series of standardized tests including slump cone test, compressive strength, split tensile strength, flexural strength, static modulus of elasticity, and Rapid Chloride Penetration Test (RCPT). The results revealed that the inclusion of fibers, particularly in hybrid form, significantly improved the mechanical properties and reduced chloride permeability. Mix M3, containing 1.0% steel and 0.3% polypropylene fibers, demonstrated the best overall performance with enhanced strength, ductility, stiffness, and durability. While fiber addition slightly reduced workability, it remained within acceptable limits due to the use of high-range water-reducing admixtures. The findings confirm that the combined use of steel and synthetic fibers in HPC not only enhances its structural performance but also greatly improves resistance to environmental degradation. This study supports the application of FRHPC in demanding infrastructure projects where high strength and long-term durability are essential.},
