Abstract: The application of self-compacting mortar into repairing work as economical repairing material with high bond strength and the prototype has been studied. The tensile bond strength of self-compacting mortar was slightly higher than that of conventional concrete mortar due to low water to cement ratio. However, water to cement ratio was not always the dominant factor for the bond strength of self-compacting mortar compared with the tensile strength of joint-less specimen. Water curing promoted the tensile bond strength remarkably from that of shield curing. Also, the replacement of cement with limestone powder promoted or kept the tensile bond strength despite of the reduction in the cement content of the mortar.
It can be concluded that the dominant factor for the bond strength of self-compacting mortar was the supply of water for the hydration of cement rather than the water to cement ratio.
That phenomenon was due to very low water to cement ratio of the self-compacting mortar itself.
