Red mud is a waste material generated during the processing of bauxite into aluminum. However, its disposal and management present significant environmental challenges. This study investigates the utilization of red mud (RM) as a partial replacement for cement in High Compressive Strength Concrete (HCSC) at 10% and 20% replacement levels. Concrete mixes were prepared and tested for compressive strength at 7 and 28 days. The results indicate that both 10% and 20% RM replacement levels produced compressive strengths that slightly exceeded those of the control mix at both curing ages. These outcomes demonstrate that RM, at these levels, can be used effectively as a cement substitute in HCSC without compromising strength development. The findings contribute to the advancement of sustainable concrete technologies and highlight the potential of red mud as a technically viable supplementary material for high-performance structural applications.
