【摘要】 本文主要对混凝土中钢筋腐蚀的机理及其测量方法的研究现状进行论述。讨论了钢筋腐蚀与混凝土碳化这两种引起混凝土构件破坏的主要因素、基本机理与特征,简要介绍了各种环境因素,尤其是氯离子与碳化对钢筋腐蚀的影响,介绍了几种钢筋腐蚀的电化学原位快速无损检测方法,分析目前钢筋腐蚀研究存在的问题并提出今后发展方向。更多还原

【Abstract】 The article has mainly introduced the present research in principle of reinforcing steel and the test methods of concrete,discussed the main factors, basic principle and feature of steel corrosion and carbonation of concrete which arose invalidation ofconcrete component, and briefly introduced a series of environment factors, especially the chloride ion and carbonation which influentthe corrosion of steel bar. Sereval kinds of electrochemical non-destroy test methods to steel corrosion were introduced. Several presentproblems of reinforcing steel research were analy sed and its development was put forward.更多还原
