Abstract: Systems and methods are provided for a forming a supersulfated cementitious material. In one embodiment, the supersulfated cementitious material may include a ladle slag and one or more sulfates obtained from various industrial sulfurization processes. The supersulfated cementitious material may further include one or more supplementary cementitious materials (SCMs). An amount of ground granulated blast furnace slag incorporated into the supersulfated cementitious material may be less than 82% while demonstrating rapid strength development.

Abstract: Methods and systems are provided for forming a cement material incorporating an industrial byproduct. In at least one embodiment, a method for forming a cement material includes maintaining a slag as an at least partially molten material and adding one or additives to modify the at least partially molten material. The method further comprises cooling the at least partially molten material to comprise a solid non-metallic fraction with a substantially amorphous molecular structure and a metal fraction that is substantively separated from the solid non-metallic fraction.
