EFFECT OF COMPONENTS FINENESS OF GROUND GRANULATED BLAST FURNACE SLAG (GGBFS) ON ITS STRENGTH EFFICIENCY IN ROLLER COMPACT CONCRETE MIXES

EFFECT OF COMPONENTS FINENESS OF GROUND GRANULATED BLAST FURNACE SLAG (GGBFS) ON ITS STRENGTH EFFICIENCY IN ROLLER COMPACT CONCRETE MIXES Abstract: ?Application of cementitious material is a well accepted supplement to enhance the strength of concrete composites. This is due to its improvement characteristics and overall economic feasibility. The present paper aims to evaluate the strength efficiency of GGBFS in Roller Compact Concrete (RCC) mixes with finenesses of 1500cm2 /gr and 2850cm2 /gr at 28 and 90 days respectively. The investigation involved assessing the effect of replacement levels of 0, 25, 50 and 75 percent of GGBFS on strength efficiency of GGBFS (k). Results show that increase in the GGBFS fineness correspondingly enhances the strength efficiency in RCC mixes.
