随着预应力高强钢材的采用和在使用中出现的问题,预应力钢材的腐蚀问题逐渐受到各国的重视,并被认为是影响结构耐久性的主要因素之一。预应力钢材的腐蚀现象,在50年代就被提出。1953年在西德 Vorarlberg 和 Donaumnster 的预应力桥梁施工时,预应力钢材在张拉后几小时和几天后突然断裂,1958年在 With the adoption of prestressed high-strength steels and the problems in use, the corrosion of prestressed steels has gradually attracted the attention of various countries and is considered as one of the major factors affecting the durability of the structures. The phenomenon of corrosion of prestressed steel was proposed in the 1950s. When prestressed bridges were constructed in Vorarlberg and Donaumnster in West Germany in 1953, the prestressed steel suddenly broke after hours and days of tension, in 1958.
