Abstract Solid-state reference electrodes were widely adopted to monitor the corrosion of reinforcement and chloride ion concentration in concrete protective layers, which is one of the core components of the durability monitoring equipment for concrete structures. In present, the existing electrodes cannot satisfy all the application requirements of solid-state reference electrodes in concrete environments. Thus, it is important to select solid-state reference electrodes with favorable comprehensive performance. In this article, the repeatability and stability of powder MnO2 reference electrode, colloidal MnO2 reference electrode, nickel ferrite (NiFe2O4) solid reference electrode, and graphite electrode were compared in simulated pore solution and mortar, respectively. The sensitivities of these reference electrodes also were compared when they were used in multiple operating conditions, such as different temperatures, pH values, oxygen concentrations, and chloride ion concentrations etc. The comprehensive properties of various solid-state reference electrodes were analyzed by weighing method. The results show that the powder MnO2 electrode has favorable reproducibility and stability, but it was not sensitive to the pH value in the concrete environment. In comparison, the NiFe2O4 solid-state reference electrode was insensitive to temperature and oxygen content. In summary, the powder MnO2 reference electrode displayed the best comprehensive properties in the simulated pore solution. For the short-term testing in mortar, slight differences were observed in the properties of the powder MnO2 electrode, colloidal MnO2 electrode, and nickel ferrite electrode, and further research needs to be performed on the long-term performance of the three electrodes in concrete environments.
