Abstract Recent trends focuses on the utilization of waste products as a partial replacement in concrete ingredients. Many mineral admixtures are already in practice such as fly ash, slag powder, silica fume etc. one such industrial byproduct is red mud which is available as a highly concentrated condition as a byproduct of bauxite purification processed. Red mud can be replaced with cement in the total binder condition and reasonable variation in the strength parameter can be recorded. To enhance the performance, hydrated lime is added to the mixes which increase the compressive strength better than conventional concrete. In this study, M30 grade of concrete is designed and red mud is partially replaced by 5, 10, 15 & 20% by weight of the cement in the total binder content. The compressive strength of the modified mixes and conventional mixes were evaluated systematically. Test results shows 10% & 15% replacement of red mud with cement records a on par and better value for both mixes with and without addition of hydrated lime.
