防冰盐腐蚀与钢筋混凝土的耐久性

DEICING SALT'S CORROSION AND DURABILITY OF REINFORCED CONCRETE

世界上不少国家， 因早年使用道路防冰盐（冬季化冰雪），造成桥梁、道路的严重破坏， 目前正在花费巨额修复， 其经济损失巨大。我国北方地区也沿用冬季撒盐或盐水化冰雪的方法，北京西直门立交桥的腐蚀破坏证明防冰盐的危害是十分明显和严重的。必须认识其危害性，采用防盐腐蚀的新技术。

Currently,there are a great many countries in their earlier years have adopted deicing salt(for melting ice and snow in winter season),have caused great damages of bridges and roads.Therefore,there are huge renovation and repair consumption spent,so that the economic loss is tremendous.In north China,our country has also adopted deicing salt for melting ice and snow in winter.The overpasses of Xizhimen in Beijing have been severely damaged,therefore the new technology of anti-corrosion should be adopted,so that their damages could be reduced or even eliminated.
