The potential use of locally sourced ground granulated blast-furnace slag (GGBFS) and commercial sodium sulfate (Na2SO4) in the development of an eco-friendly sulfate-activated binder (SAB) was investigated in this study. The influence of Na2SO4 contents (, , , , and by mass of GGBFS) as a crucial sulfate activator on mechanical strength and durability performance of the SAB samples was evaluated through the tests of compressive strength, porosity, chloride ion penetration, and ultrasonic pulse velocity. |
