Abstract: Freeze thaw action is one of the important factors affecting the durability of concrete. Externally bonded fiber-reinforced polymer (FRP) is widely used in the reinforcement and repair of damaged concrete structures due to its significant effect in improving concrete performance. The aim of this study is to investigate the improvement effect of externally bonded basalt fiber-reinforced polymer (BFRP) on the performance of concrete after freeze-thaw cycles. By conducting 25, 50, and 75 freeze-thaw cycles on concrete specimens, the specimens experienced varying degrees of damage and were reinforced with cost-effective basalt fiber (BFRP). By conducting axial compression tests, the bearing capacity, reinforcement effect, and failure mode of freeze-thaw specimens were compared under different BFRP reinforcement methods, including unfrozen, unreinforced after freeze-thaw, reinforced before freeze-thaw, and other conditions. The results indicate that BFRP cloth reinforcement technology can significantly improve the bearing capacity of freeze-thaw damaged specimens. Under the same reinforcement area, the reinforcement effect of 3 strips with intermittent wrapping is better than that of 2 strips with intermittent wrapping; In addition, the method of "strengthening first and then freeze-thaw" can effectively slow down the deterioration of concrete caused by freeze-thaw cycles. This study can provide reference for the mechanical properties research of BFRP cloth reinforced freeze-thaw damaged concrete. Reinforcing before freeze-thaw cycling effectively mitigates the degradation of concrete caused by freeze-thaw action. These findings provide valuable insights for further research on the mechanical properties of freeze-thaw-damaged concrete reinforced with BFRP.
