Abstract: The concrete is being used as 2nd most essential material in the world and most of the companies are in need of economical concrete by replacing cement by cementitious material. This papers show the preparation of concrete using granite powder(brought from muddenahally, Chickaballapur) as a partial fine aggregates at a rate of 0%, 5%, 10%, 15%, 20% and 25% and cement is replaced using 10% fly ash, 10% GGBS, 7.5% silica fumes and 0.9% super plasticizer used too. The beams of size 700mmX150mmX150mm are casted of M40 with w/c ratio 0.42 and cured for a curing period of 7, 14, 28 and 56 days. The test results shows increase in flexure strength till 20% of granite powder replacement and rest are equal to normal concrete. Thus, Granite Powder acts as a best replacement to natural sand till 25%.
