        abstract = {The increasing demand for sustainable construction materials has encouraged the use of industrial by-products and alternative reinforcement in concrete. This study investigates the mechanical and structural performance of concrete incorporating stainless steel slag (SSS) as a partial replacement for coarse aggregate and Glass Fiber Reinforced Polymer (GFRP) bars as an alternative to conventional steel reinforcement. In Phase 1, coarse aggregate was replaced with stainless steel slag at proportions of 20%, 30%, and 40% by weight, and the fresh and hardened properties of concrete such as workability, compressive strength, split tensile strength, and flexural strength were evaluated. The results indicated that the inclusion of stainless-steel slag improved the strength characteristics of concrete up to an optimum replacement level of 30%. Based on the optimum mix, Phase 2 focused on the flexural behavior of reinforced concrete beams. Four reinforced concrete beams of size 150 mm × 150 mm × 1300 mm were cast: (i) conventional concrete with steel reinforcement, (ii) conventional concrete with GFRP bars, (iii) concrete with 30% stainless steel slag and steel reinforcement, and (iv) 30% stainless steel slag concrete with GFRP bars. The beams were tested under flexural loading to evaluate their load–deflection behavior, cracking characteristics, and ultimate load capacity. The study aims to determine the effectiveness of stainless-steel slag as a sustainable aggregate replacement and assess the structural performance of GFRP-reinforced concrete beams. The results contribute to the development of durable, corrosion-resistant, and environmentally sustainable concrete structures.},
