Abstract: Accelerated method of mix design is very effective method for producing high performance characteristics in early ages of concrete. Accelerated curing of concrete hastens the process of hydration of cement and as a result the essential portion of the strength to be attained in 28 days under normal curing conditions is achieved within a short period. In 1980’s there is no awareness of using Ground Granulated Blast Furnace Slag (GGBS) and Silica fume. In accelerated method of mix design, till now there is a correlation for plain concrete only. In this study, the accelerated curing method was done by using the combination of GGBS and Silica fume and by varying three different water-binder ratios such as 0.3, 0.4 and 0.5, whereas the percentages of GGBS have been varied from 90%, 80%, 70%, 60% and 50% by adding 5% of silica fume for the weight of cement. To achieve above mentioned in this present study around 108 number of standard lab size of cubes (150×150×150mm) have been tested under compression. The performance of blended concrete with accelerated curing method has been accessed through compressive strength, effect of GGBS percentage and effect of water-cement ratio. In this study, the correlations will be developed among the boiling water strength, 28 days and 90 days of GGBS and Silica fume.
