The effects of dry-wet cycles， replacement rate of recycled coarse aggregates and volume fraction of waste fiber on chloride transport performance of waste fiber recycled concrete were studied， and the chloride transport mechanism was analyzed. The results show that with the increase of replacement rate of recycled coarse aggregate， the chloride erosion resistance of recycled concrete becomes smaller under dry-wet cycles. The addition of waste fiber can improve the resistance of chloride erosion of the recycled concrete. The dry-wet cycled condition show a more significant effect on the content of free chloride ion with different recycled aggregate replacement rates. Under the dry-wet cycles， the content of free chloride increases first and then decreases with the increase of the erosion depth. There is a linear correlation between free and total chloride content， and the accuracy of coefficient representing chloride binding capacity is 0.001. In the actual engineering durability design， the effects of replacement rate of recycled coarse aggregate and the volume fraction of waste fiber on chloride binding capacity can be ignored.
