摘要

已经评估了在化学环境中估计钢筋混凝土结构腐蚀的技术,并在利物浦大学的实验室和中国和英国的几个不同的化学工厂进行了测量。如果有可能与钢筋直接接触,那么线性极化电阻(LPR)测量是最适合采用的技术。在不可能与钢筋接触的情况下,已经发现在化学环境中,混凝土电阻率测量是一种比电位测量或绘图更好的估计腐蚀的技术。

Corrosion assessment of reinforced concrete structures in corrosive environments in Chinese chemical industry
Abstract Techniques have been assessed for estimating corrosion in reinforced concrete structures in chemical environments, and measurements have been carried out in the laboratory at the University of Liverpool and at several different chemical factory sites in China and the UK. If it is possible to make a direct contact to the steel reinforcement, then linear polarisation resistance (LPR) measurement is the most suitable technique to employ. Where it is not possible to make contact with the reinforcement, it has been found that concrete resistivity measurement is a better technique in chemical environments for estimating corrosion than potential measurement or mapping.
