Effect of SCBA and GGBFS on the performance of binary and ternary blended concrete

Abstract

The present studies focus on the characteristics of binary and ternary concrete in plastic and hardened stage for a mix of grade M25. Two mineral admixtures were used, sugarcane bagasse ash (SCBA) and ground granulated blast furnace slag (GGBFS). In preparing binary and ternary blended concrete, these admixtures partially substituted cement. Cement was replaced with SCBA and GGBFS, with the substitution percentage being 15%, 20%, 25%, and 30% by mass. Fresh properties were evaluated in terms of slump cone and setting time. Moreover, the mechanical characteristics were assessed concerning the strength of concrete in compression, split, and flexure. The microstructural properties were investigated in terms of scanning electron microscope (SEM) images. The experimental result indicated that the inclusion of SCBA and GGBFS improves workability and strength in compression while strength in the split and flexural hampered in binary as well as ternary concrete.
