“…Unfortunately, the short service life and fragile structure determine these reference electrodes can not be used in the field. Recently, several embeddable REs, such as MnO 2 [43][44][45][46][47] , Metal-Metal Oxide (MMO) [48,49] and NiFe 2 O 4 [50] , have been prepared and attempted to apply in RC structures. European Federation of Corrosion (EFC) has also reviewed the electrochemistry and characteristics of embeddable reference electrodes for concrete, and reported the service status of the six kinds of embeddable REs which have been implanted in Gimsøystraumen Bridge (in Norway) few years ago [51] .…”

Prestressed concrete beams of size 150 × 150 × 1000 mm were designed, and two bonded cold-drawn 7 mm steel wires were stressed at 70% UTS under service conditions before concreting. e beams were cast with M40 grade concrete mix with various percentages of chlorides ranging from 0, 1, 2, and 3% by weight of cement and cured for 28 days. After 28 days, the stretching forces were released, the prestressing steel wire was allowed to regain its original length, the tensile stresses were transformed into a compressive stress in the concrete, and the stress corrosion behavior was assessed. Stress corrosion cracking (SCC) is due to the simultaneous action of stress, corrosive media, and material properties. e stress corrosion behavior of ungrouted pretensioned steel was assessed by using various electrochemical techniques such as electrochemical noise, open-circuit potential measurement, AC impedance, and potentiodynamic polarization measurements. e same experiments were conducted for rebars embedded in the concrete beam with various percentages of chlorides ranging from 0, 1, 2, and 3% by weight of chloride. After 30 days of exposure, the beams were tested for their flexural strength measurements to find out the load-bearing capacity.

“…Castro 9 and Duffo 2 have adopted the metal-metal oxide activated titanium rod as the RE used in concrete, but the potential of this electrode was dependent on pH value. MnO 2 RE has been introduced as the embeddable RE in concrete, 8,10,11 however, it didn't belong to the traditional categories of REs because the potential of MnO 2 RE could not be described by a theoretical formula or equation.…”

Solid Ag/AgCl reference electrodes (RE) with different electrolytes were assembled and characterized in concrete. The performances have been studied with respect to known RE. And the corrosion states of steel have been investigated with respect to embedded and external REs by different electrochemical techniques. Results revealed that half-cell potential of 0.1, 1 and 4.18 M AgCl RE was 20 mV, −30.5 mV and −54.6 mV, respectively. In addition, 4.18 M AgCl RE exhibited the minimum potential drift, the smallest temperature coefficient value and the best reversibility. These corrosion parameters such as rebar potential, corrosion current density (I corr ) and charge transfer resistance (R ct ) obtained for steel with respect to these embedded AgCl REs could clearly differentiate the active condition of steel from the passive condition. Besides, I corr and R ct obtained for steel with respect to external SCE were usually 2 or 3 times larger than these embedded AgCl REs. In such cases embedded AgCl REs could accurately investigate the corrosion rate of steel in concrete. Moreover, the 4.18 M AgCl RE was recommended to monitor the corrosion condition of steel in concrete structure.
