Abstract: Aggregates obtained by breaking down waste concrete are called recycled aggregates (RA). In consistence with sustaining development, the recycled aggregate concrete (RAC) that is made from recycled concrete aggregates could be a perfect solution to resource and environment preservation. Because RAC is made from different properties material, so its fatigue behaviour is different from other concretes. Therefore, on the basis of experimental research, the fatigue behaviour and microstructure of recycled concrete are studied in this paper.
The present paper deals with investigations on fatigue behaviour of the axial and eccentric compression performance of recycled aggregate reinforcement concrete specimens with contain recycled aggregate proportion of 0%, 50%, 100%. Then micro-structural observations of the specimens by means of scanning electron microscopy (SEM) were obtained. Based on the analysis of experiment results, it can be proved that it is feasible to apply recycled concrete to practical engineering.
