Abstract: The current work focused on utilization of granite powder as a mineral admixture in concrete. Granite stones are highly precious natural resource, which are used in construction industries. While crushing or cutting of granite stones more than half of the granite wasted in the form of granite dust or powder. Utilization of large amount of granite powder (GP) in concrete as replacement to the cement can control the pollution due to cement industries. The current work granite powder was replaced by cement with 0% to 20% with interval of 5%. Based on the results, the optimum replacement of granite powder was 15% and which is kept as constant. Silica fume (SF) used as a ternary mineral in current mix and it is replaced by cement was 0% to 8% with interval of 2%. The optimum replacement of silica fume in granite powder concrete was 6%. The presence of higher content of calcium and silica in mix helps to develop C-S-H gel formation; this is reason for enhancement of mechanical properties in present concrete mixes.
