摘要
对结构混凝土进行耐久性检测、评估是掌握结构实际状况、制订修复或维护策略的基础,对延长以混凝土结构为主体的基础设施使用寿命具有重大的实际意义.综述了既有混凝土结构耐久性检测的主要内容,并对混凝土渗透性、钢筋锈蚀情况等影响结构耐久性的关键参数的无损检测技术进行了介绍.
The non-destructive testing (NDT) of concrete durability in structures is a fundamental base of keeping track of structures' real condition and making right repair or maintenance strategy, which is very important to extend the service life of those concrete infrastructures. In this paper, the main NDT technology related to the durability inspection was reviewed and two key testing methods, inspection of corrosion and permeability of concrete, were emphasized.
