In this study, to evaluate bond behaviour between high strength concrete with recycled aggregate and fiber reinforced polymer ( FRP) bar, 36 specimens were manufactured using substitution rate of recycled aggregate, compressive strength of concrete, arrangement direc tion of CFRP or GFRP bar. Concrete cubes were manufactured by referrin g to the standards in KS F 2441, ASTM 234 and CAS-S802. Bond stress and slip of specimens did not show certain standards and bond stress had a decreasing trend with increase in substitution rate of recycle d aggregate. Also for horizontal specimens with 30 % substitutio n rate of recycled aggregate, top specimen had higher bond strength than bottom specimen. For specimens with 100 % substitution rate of recycl ed aggregate, bottom specimen had higher bond strength than top s pecimen. This study suggests that the difference according to the settl ement of an aggregate is not large.
