Abstract: Heavy-density concrete plays a pivotal role in providing structural integrity and radiation shielding in critical infrastructure. However, exposure to acidic environments poses a significant challenge, potentially compromising the material's durability and mechanical properties. This research examines the mechanical and non-destructive properties of heavy-density concrete produced by integrating grit iron scale aggregates as coarse aggregate in concrete and the utilization of silica fume as a supplementary cementitious material. The experiments involve preparing samples using 25% and 50% Heavy Weight Grit Iron Scale (HWGS) Aggregate along with 15% silica fume. Concrete specimens were tested for slump, compressive strength and rebound hammer after 28 days of curing. The water-cured specimens were exposed to 10% of sulfuric acid (H2SO4). The findings indicated that concrete containing 25% HWGS exhibited superior acid resistance in comparison to the other concrete mixes while achieving maximum compressive strength.
