The interfacial transition zone for tensile bond strength concrete repair system plays a key role. The State of concrete impact to the tensile bond of repair system, the influence law for tensile bond of repair system is water saturation state natural state dry state. After the interface treatment, the tensile bond of repair system is higher when the liquid and two-component interface agent is semi-arid than when the liquid and two-component interface agent is totally-arid. By SEM observation microscopic of repair system can be seen as a water saturation state, semidry conditions for the interface agent, two interface of repair systems connection between the three materials more closely.
