| 摘 要： | 通过对四种不同配比混凝土进行冻融循环（0、50、150次）和氯离子侵蚀试验，研究冻融作用对混凝土中氯离子侵蚀的影响。结果表明，冻融循环使混凝土孔隙率增大，它是混凝土损伤的动力源，为氯离子侵蚀创造更为有利的条件；冻融次数越多，氯离子侵蚀越严重。

| Abstract: | Four kinds of different mixture-ratio concrete were tested after being exposed to freeze-thaw action(respectively 0,50,150 cycles) to study the effect of chloride erosion into concrete.The monitored results show that the freeze-thaw action increases the porosity of concrete,which is the fundamental cause of concrete damage,and promotes the chloride erosion into concrete.The more times concrete is exposed to freeze-thaw action,the more serious the chloride erosion into concrete will become. |
