Abstract
In alkali-activated slag/fly ash based concrete (AAC), ground-granulated blast-furnace slag (GGBS or GGBFS) plays an important role in increasing the early strength of concrete and accelerating the geopolymerization of fly ash (FA) at room temperature. Therefore, the quality of GGBFS (chemical composition, fineness) has a significant influence on the mechanical properties of AAC. In this paper, through theoretical analysis and experimental results, the effect of the fineness of GGBFS on the compressive strength and tensile strength was investigated.
