        abstract = {The global construction industry is facing increasing challenges related to sustainability, resource depletion, and effective waste management. In response, the use of recycled coarse aggregates (RCA) and fiber reinforcement in high-strength concrete (HSC) has emerged as a viable solution to enhance material performance while minimizing environmental impact. This study investigates the behavior of steel fiber-reinforced high-strength concrete (SFRHSC) incorporating RCA at varying steel fiber content levels of 0%, 0.2%, 0.4%, 0.6%, 0.8%, and 1.0% by volume. A detailed experimental analysis was conducted to assess key properties, including workability, mechanical performance, and durability. Mechanical properties such as compressive strength, flexural strength, split tensile strength, and density were measured to evaluate the impact of steel fiber addition. Results demonstrated that increasing steel fiber content improved strength properties, with optimal fiber content achieving maximum compressive and tensile performance. Durability properties, including water absorption, water permeability, and resistance to acid attack, were also examined to determine the material’s long-term performance. SFRHSC demonstrated enhanced durability with higher fiber content, indicating improved resistance to environmental degradation. Additionally, microstructural analysis using Scanning Electron Microscopy (SEM) provided insights into the bonding behavior between the RCA, cement matrix, and steel fibers, revealing a denser, more cohesive internal structure. This research highlights the potential of SFRHSC as a sustainable, high-performance construction material that offers improved workability, superior mechanical strength, enhanced durability, and optimized microstructural properties.},
