Abstract
In this study, we investigated the hydration characteristics of the binder which mixed gypsum to rapidly cooled Ladle furnace slag, a by-product generated from steel industry. The results of XRD and SEM analysis showed that the binder mixed with gypsum created large amounts of Ettringite after 1 day. Compared to the binder using only the rapidly cooled Ladle furnace slag, the binder mixed with gypsum had a decreasing “total porosity” and an increasing micro-pore distribution due to continuous hydration reaction over the age, although it had large pore initially.
