本文阐述了对钢筋混凝土结构中钢筋腐蚀率评价的研究。可以测量混凝土的电阻率和电压以获得钢筋的实际腐蚀率。讨论了现场测量混凝土结构电阻率的方法以及在现场应避免的失误。最后讨论了直接测量腐蚀率的方法以及在现场采用这些方法时必须克服的困难。
This article describes the evaluation of the corrosion rate of steel bars in reinforced concrete structures. The concrete resistivity and voltage can be measured to obtain the actual corrosion rate of the steel bar. Methods for measuring the resistivity of concrete structures on site and errors that should be avoided at the site were discussed. Finally, the methods for measuring corrosion rates directly and the difficulties that must be overcome when these methods are used in the field are discussed.
