RC structures used the recycled aggregate concrete composed of recycled aggregate will evidently become concrete waste in due time. Such concrete waste has to be recycled as well in order to reduce concrete waste. In other words, the ideal goal is to use the recycled aggregate continuously. This paper investigated from two types of experiments (experiment I and II) that the recycled aggregate concrete composed of repeatedly recycled aggregate is able to use as a appropriate material for aseismatic performance of RC frame. In experiment I, the influence of the recycling frequency on the properties of recycled coarse aggregate was evaluated. This experiment showed that recycled coarse aggregate changes to mortar after being recycled many times. Experiment 11 used RC beam specimens made of recycled aggregate concrete itself composed of coarse aggregate made from mortar, which represented the condition of repeatedly recycled coarse aggregate. Such specimens were tested on the flexural, shear, and bond failure and it was investigated that the repeatedly recycled aggregate concrete could be used for aseismatic performance of RC frames.
