This paper discusses on strength and self-restorative capacity of GBFS (granulated blast furnace slag) under several conditions. In laboratory tests, GBFS specimens are cured in three types of solutions (plain water, seawater, and calcium hydroxide solution) and the change in unconfined compressive strength and hydration reaction of GBFS are investigated. It is confirmed that the strength of GBFS increases with curing duration due to hydration reaction regardless of its history of shear failure. When GBFS is once collapsed after curing, the shear strength increases up to 60% of those without shear failure. In addition, a prediction method of the strength of GBFS due to the self-restoration is proposed.
