  • Abstract:
  • The replacement of coarse aggregate with iron slag in concrete production has gained attention as a sustainable construction practice. This study investigates the potential of using iron slag, a by-product of the iron and steel industry, as a partial or complete substitute for conventional coarse aggregates in concrete. The experimental work involved analyzing the mechanical properties, durability, and workability of concrete mixes with varying proportions of iron slag (0%, 15%, 30%, 45%,) replacing coarse aggregates. The results demonstrate that concrete incorporating iron slag exhibits improved compressive strength and durability due to the slag's dense structure and high toughness. However, slight variations in workability were observed, which could be mitigated through the use of admixtures. The study concludes that iron slag can be effectively utilized as an alternative aggregate, promoting waste management, reducing the demand for natural aggregates, and enhancing the sustainability of construction practices. Further research is recommended to evaluate long-term performance and environmental implications. This approach aligns with green construction principles, reducing industrial waste and minimizing environmental degradation caused by aggregate extraction.
