        abstract = {The rapid depletion of natural aggregates and the growing environmental impact of industrial waste disposal have necessitated the development of sustainable alternatives in concrete production. This study investigates the feasibility of utilizing steel industry by-products—Coal Bottom Ash (CBA) as a partial replacement for fine aggregates and Blast Furnace Slag (BFS) as a partial replacement for coarse aggregates—in M25 grade concrete. Five trial mix proportions were developed, incorporating varying replacement levels of CBA and BFS (10%, 20%, 25% and 40%) and compared against a conventional control mix. Comprehensive experimental investigations were conducted on fresh and hardened properties, including workability, compressive strength, split tensile strength, flexural strength and durability characteristics in accordance with IS standards. The results indicate that optimum replacement levels improve workability and enhance long-term strength due to the porous texture of CBA and the dense, durable nature of BFS. Moderate replacement levels (20–25%) demonstrated the best balance between strength and sustainability, with strength values comparable to or exceeding the control mix. The study confirms that significant portions of natural aggregates can be substituted with steel industry by-products without compromising structural performance. This approach promotes resource conservation, reduces environmental pollution and contributes to the development of eco-friendly concrete suitable for sustainable construction applications.},
