Research Abstract	It is needed to be established the maintenance method for ASR deteriorated concrete due to an excessive expansion. Main purpose of this study is to be clarify the mechanical behavior of ASR deteriorated concrete that made with various aggregate. The expansion of those concrete were over 0.8%. As results, it is cleared that the effect of type of reactive aggregate on the mechanical property is not significant. Furthermore, it can be recommended that the minimum value was designed by using the these obtained mechanical data of ASR deteriorated concrete in order to use for the evaluation the performance of ASR deteriorated concrete member.
