초록

This study was conducted for investigating effect of retardation time of secondary placement on shear bonding strength. Evaluation experiment on the shear bonding performance of UHPC(180MPa level concrete) was conducted according to retardation time and size of specimen. As a result, the smaller the size of specimen, the weaker the measured bonding performance of specimen. Also, comparing specimen which is o minute occurrence time of cold joint with specimen which is after 15 minutes, it showd 70% lesser shear bonding strength.
