In accordance with the national trend, although research about deflection of reinforced concrete that use nature aggregate in domestic research had been studied, they have prescribed to use the recycled aggregate compulsorily in case of over construction scale as an applicable construction of "Law about contract that the nation should be a contracting party" since 2005. However, although it has still obligated to use the recycled aggregate based on "Recycled aggregate quality standard" by Construction and Transportation Ministry, actually its study on long-term deflection of recycled aggregate is an unsatisfied situation. Therefore, the purpose of this study is to resolve the technical problems for cycling concrete through its experiment and analysis of long-term deflection by the substitution rate of recycled aggregate.
