| Abstract: | In the first instance the influence of the position of the repaired interface on the bonding strength of new to old concrete was proposed and systematic researched.Five positions of the repaired interface,namely upper repaired,down repaired,upper inclined repaired,down inclined repaired and side repaired were included in this experimental research.Two kinds of new to old concrete age differences(three months and three years) and various methods of interface treatment and primers were involved. |

| Keywords: | new to old concrete position of the repaired interface bonding strength |
