Recently, natural aggregate resource depletion are being raised due to the pollution issues regarding the construction waste generated during demolition of building deterioration and the supply issues of aggregates. Recycled aggregates are beingused as a solution to these issues, but the quality and durability/structural performanc e issues are the restriction of application. This study conducted a c omparative evaluation of bond behaviour according to the reinforcing ba r type and substitution rate of recycled coarse aggregate mixed with hi gh strength concrete. That was carried out to verify the applicability o f recycled coarse aggregate concrete as a structural member. Seventy-tw o specimens were manufactured with variables of recycled aggregate subst itution rate (0, 30, 50 and 100%), reinforcing bar arrangement direc tion and reinforcing bar types. The bondstress and the slip relation of reinforcing bar and concrete in high strength concrete usin g recycled aggregate were found to have little influence on the reinfo rcing bar arrangement direction, location and substitution rate.
