影响钢筋混凝土结构物耐久性的因素中,最常见的是钢筋锈蚀引起的破坏,已成为世界性问题,许多国家都在积极采取防护措施。钢筋锈蚀的防护措施目前已有多种,如耐蚀钢筋、钢筋涂层、混凝土外涂层、阴极保护等,其中改进混凝土自身的防护能力被认为是最简易而行之有效的。苏联关于钢筋阻锈剂的专著中阐明:提高混凝土保护钢筋性能的最有效的方法是掺钢筋阻锈剂。日本自1973年开始使用钢筋阻锈剂,现在已成
Among the factors influencing the durability of reinforced concrete structures, the most common is the damage caused by corrosion of steel bars, which has become a worldwide problem. Many countries are actively taking protective measures. There are many kinds of protective measures for corrosion of steel bars, such as corrosion-resistant steel bar, steel bar coating, concrete outer coating, cathodic protection, etc. Among them, improving the protection of concrete itself is considered to be the simplest and most effective. The Soviet Union’s monograph on reinforcing steel rust inhibitors states that the most effective way to improve the performance of concrete protection steel reinforcements is to add reinforcing steel rust inhibitors. Japan started using steel corrosion inhibitors since 1973 and is now
