It is well-known that a typical method of using demolition structural concrete is to recycle it into coarse (RCA) and fine (RFA) aggregates, which are then used to replace the natural coarse and fine aggregates to make concrete, named recycled aggregate concrete (RAC). This provides a win-win solution in mitigating the environmental problems regarding huge depletion of natural aggregates and disposal of large number of demolition waste. Compared with the extensive experimental and theoretical studies on the material and structural behaviors of RAC by replacing natural coarse aggregate with RCA, the studies on the behavior of RAC with RFA were relatively limited. Ergo, this paper studied the material property of RAC with RFA and behavior of carbon fibre-reinforced polymer (CFRP) confined RAC with RFA. A total of 4 CFRP-confined normal concrete (concrete with natural aggregate) and 8 CFRP-confined RAC with RFA were prepared and tested under axial compressive load. Results showed that the stress-strain behavior of CFRP-confined RAC with RFA is quite different to that of CFRP-confined normal concrete due to the unique physical and chemical properties of RFA. The authors’ previous model considering the effect of packing structure of concrete has been adopted to predict the stress-strain behavior of specimens. Comparing the predicted with experimental results, it is clear that the model can predict the stress-strain relationship of CFRP-confined normal and recycled concrete well.
