The purpose of this study is to explore the mechanical properties of concrete at different curing ages after freeze-thaw cycles in most areas of the plateau where freeze-thaw cycles exist. By comparing the compressive strength and splitting strength of concrete at different curing ages after different freeze-thaw cycles, the influence of curing age changes on the mechanical properties of concrete after freeze-thaw damage was analysed. The results show that the compressive strength and splitting strength of concrete can be significantly increased by increasing the curing days of concrete with the same number of freeze-thaw cycles, and sufficient curing age has a significant effect on reducing the influence of freeze-thaw cycles. Under the condition of the same curing days, with the increase of the number of freeze-thaw cycles, the compressive strength of concrete will first increase and strengthen at 50 cycles, and then start to weaken continuously. The splitting strength will continue to decrease with the increase of freeze-thaw cycles.
