The research findings of an experimental study on the axial compressive behavior of carbon fibre reinforced polymer (CFRP) confined basalt fiber (BF) reinforced recycled aggregate concrete (RAC) are presented in this paper. Six CFRP confined BF reinforced RAC (BFRC) short columns were tested under axial compression. The effects of the recycled concrete aggregate (RCA) replacement ratio and CFRP constraint form were studied. The failure mode, stress-strain curve, finite element model and ultimate bearing capacity prediction are analyzed in detail. The results show that the failure modes of unconfined BFRC are similar, while those of CFRP-confined BFRC are different. CFRP constraints can effectively improve the bearing capacity and deformation capacity of BFRC square columns, and the degree of improvement is positively correlated with the thickness and the confined area of CFRP. Based on the experimental data, a simple prediction model of ultimate bearing capacity is established. The model has good accuracy.
