抄録

 From the results of site observations, granulated bl ast furnace slug (GBFS) is solidifying w ith time. It takes a long time to solidify the whole of GBFS, b ecause GBFS observed was no t fully solidified in 18 months. It means if GBFS is used with relied on its solidification, a treatment for acceleratin g the solidification of GBFS is needed. For discus sing this point, the condition for solidifying GB FS is checked in series of laboratory experiments. It was clarified that adding micro powder of furnace slag to GBFS is effective for accelerating the solidification of GBFS unde r sea water. Failure crite ria of solidified GBFS are explained with internal friction a ngle and cohesion intercept. Failure criteria for residual condition of GBFS are explained by internal friction angle only. These parameters can be estimated from a single triaxial experiment.
