摘　　要：冻融破坏是影响混凝土耐久的因素之一。为研究冻融循环对混凝土耐久性的影响,开展了相关试验。通过对试件进行冻融循环试验,研究冻融循环对混凝结构耐久性的影响。试验结果表明:温度越低对混凝土耐久性影响越大;混凝土强度等级越高,冻融破坏对混凝土耐久性的影响越小。Freeze-thaw failure is one of the factors affecting concrete durability.To study the impact of freeze-thaw cycles on concrete durability,relevant tests have been conducted.By conducting freeze-thaw cycle tests on the specimens,the influence of freeze-thaw fishing on the durability of concrete structures was studied.The results indicate that the lower the temperature,the greater the impact on the durability of concrete;the higher the strength grade of concrete,the smaller the impact of freeze-thaw failure on the durability of concrete.
