This study investigated on mechanisms of peeling off in epoxy resins bonded repairing-strengthening materials. According to the experimental test, elasticity modulus of mortar indicated 16～26(GPa), and that of epoxy resins was around 45.3～220(GPa). In addition,
steel plate for repairing-strengthening materials indicated 338(GPa), while Carbon fiber Bar was 34.1(GPa). This value of each materials having different modulus was announced in this paper. Furthermore, thermal expansion coefficients of each materials also had different value, such as 10～13με/℃ of mortar, 41～54με/℃ of epoxy resins, 11.93με/℃ of steel plate and -1.68με/℃ of Carbon fiber Bar, respectively. For the properties of dry shrinkage, an increase of mixture proportion resulted in higher shrinkage value of the mortar, and the increase of flow also exhibited higher shrinkage ratio.
