Concrete is the most broadly utilized construction development material in structural building industry in view of its high structural quality and solidness. The civil industry is always searching for supplementary cementitious material with the target of lessening the strong waste transfer issue. Therefore to overcome these issues there is a need of financially savvy, elective and imaginative materials. It is additionally important to accomplish extensive quality. To overcome from this emergency, the utilization of SCMs is gaining advantages because of different preferences, for example, enhanced workability, higher compressive Strength, better durability and so forth when such SCMs are consolidated in concrete, the hydration process is affected by the physical and compound properties of SCMs utilized and are reflected in quality advancement. In this study, comprehensive effort is made to determine efficiency factor of GGBS using regression analysis. It’s based on the consideration that efficiency factor depends on GGBS percentage. It is found that efficiency factor goes on decreasing by increasing GGBS percentage in concrete made with GGBS. Characteristics of fresh concrete that is workability is improved by increase in the GGBS percentages in concrete. Rate of development of strength of GGBS concrete is slow for 7 days and for 28 days, development of strength is satisfactory.
