目的-腐蚀传感器和网络是获取钢筋混凝土结构腐蚀信息和识别钢筋混凝土结构腐蚀状态的最有效技术。然而，参比电极是腐蚀监测传感器在腐蚀测量过程中提供电位控制基线的关键元件。因此，本文的目的是为腐蚀传感器提供新型的固态参比电极。设计/方法/途径-固态Ag/AgCl参比电极已经制备。结果表明：参比电极的平衡电位和温度系数分别为3.64± 1 mv（vs. SCE）（25°C）和−0.51 mv/°C±0.03 mv/°C）。此外，极化曲线呈现出三个阶段的特点，作为极化。
Purpose – Corrosion sensors and networks are the most effective techniques to obtain the corrosion information and recognize the corrosion status of reinforced concrete structures. However, reference electrode is the key element to provide the baseline for potential control of the corrosion monitoring sensors during corrosion measurement process. Therefore, the purpose of this paper is to provide the novel solid‐state reference electrode for the corrosion sensors.Design/methodology/approach – A solid‐state Ag/AgCl reference electrode has been prepared. Furthermore, the performance of the reference electrode, such as stability, temperature response, anti‐polarization and influence of the concrete admixture, has been investigated.Findings – The results indicate that the balance potential and the temperature coefficient of the reference electrode are 3.64±1mv (vs. SCE) at 25°C and −0.51 mv/°C±0.03 mv/°C, respectively. Furthermore, the polarization curve exhibits characteristics of three stages as the polariz...
