摘要
混凝土的耐久性,特别是高性能混凝土(HPC)的耐久性一直是混凝土行业关注的课题。但迄今为止,对HPC耐久性的检测、评价、设计一直没有统一的标准。电学和电化学技术在混凝土耐久性中的应用越来越受到重视。本文使用电学和电化学技术来检测混凝土的腐蚀、增强混凝土及评估混凝土的渗透性、保护或使已碳化或受污染的混凝土再生。并评述了这些进一步要做的工作。
The durability of concrete, especially the high performance concrete, is really a popular topic in concrete field. However, up to this date, there is no universal standard method for detection, evaluation and design for durability of HPC. Fortunately, the applications of electrical and electrochemical techniques to concrete durability becomes more and more attractive. In the present paper, the applications of electrical and electrochemical techniques to the determination of corrosion, probability of reinforcement, evaluation of permeability of concrete, and protection and rehabilitation of contaminated or carbonated concrete, as well as the advantages and disavantages of these techniques, are briefly reviewed. Work further to be done is also discussed.
