In consistent with sustaining development, circularly utilizing the scrap concrete was an important measure for country and human beings. With the development and extensive application of Recycled aggregate concrete (RAC), it, as a structure, certainly would be attacked by unfavorable environments and occurred destroy or invalidation, such as fatigue (vibration load of vehicle or equipment). But, its fatigue behavior is different from other concretes as a result of different property of the aggregate of recycled concrete and other concrete. In order to apply RAC more effectively, it is necessary to study its properties especially for those aggregates from earthquake-stricken area for post-earthquake reconstruction. Therefore, on the basis of experimental research, the fatigue behaviors and microstructure of recycled concrete are studied in this paper. The present paper deals with investigations on fatigue behavior of the axial and eccentric compression performance of recycled aggregate reinforcement concrete specimens with contain recycled aggregate proportion of 0%、50%、100%, when specimens were effected by constant amplitude sine wave fatigue load imposed from 110kN~190KN with 5Hz frequency. Then the expansion and diversification of RAC cracks were real time was watched. Based on the analysis of experiment results, it can be proved that it’s feasible to apply RAC to practical engineering.
