ABSTRACT
The influence of different source materials, sodium hydroxide concentration, and different binder content on the strength of geopolymer concrete is studied in this work. There are scarce studies on the strength of GPC with different binders, A/B ratios under different curing processes, which is a novelty in this work. Hence, this study investigates the strength of GPC with (360kg/m3 & 400kg/m3) and alkaline-binder ratios of (0.45 & 0.5) under different curing. Furthermore, 144 cubes were cast to find the strength increase when 50% of GGBS was substituted with flyash. Consequently, increased GGBS content reduces workability, and outdoor curing for a combination of flyash and GGBS boosts strength and compatibility. Microstructural behavior of the materials studied using SEM and XRD. In a nutshell, GGBS affects the strength and workability of GPC under both situations. Therefore, despite the most substantial potential for oven curing, specimens can be cured in practical applications.
