Abstract: This paper present the experimental study of CDA and RHA as partial replacement of ordinary portland cement in M:15 mix proportional ratio 1:2:4 is used and tested for consistency limit ,setting time, workability of CDA and RHA with ordinary portland cement .cement was replace with CDA and RHA by weight of 5%,10%,15%,20%,25% respectively in concrete. Compressive strength test was carried out on 150x150x150mm3 concrete cube after 7, 14, and 28 days curing. It was observed that optimum content of CDA and RHA is 5% at that content maximum compressive strength is achieved. While workability decreases when increasing % of CDA and RHA in concrete and setting time also increases by increasing replacement in cement.
