ANALYSIS OF STRENGTH OF CONCRETE BY DETERMINING EFFICIENCY FACTOR OF GROUND GRANULATED BLAST FURNACE SLAG

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 and compressive strength depends on water binder ratio. 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.
