TL;DR: In this paper, the steady state polarization curves and electrode impedances were measured during the dissolution of iron in solution acidified by the addition of, and the experimental results were quantitatively interpreted by computer simulation on the basis of a reaction model including three dissolution paths.

TL;DR: In this paper, four series of reinforced concrete specimens have been studied over 3 years exposure in a 100% relative humidity atmosphere, and the results confirmed previous results obtained in alkaline medium, i.e., the redox activity in the rebar's oxides layer greatly influences the electrochemical behaviour of rebars in the passivity potential domain.

TL;DR: In this article, a low scan rate cyclic voltammetry performed over the entire electrolyte stability domain, allows for establishing the influence of the redox activity developing in the oxides layer on the electrochemical behaviour of the system and, thus, to get valuable information on the applicability of classical electrochemical techniques employed to assess corrosion of steel in concrete.

TL;DR: In this article, the use of the electrochemical impedance spectroscopy (EIS) was used to identify different processes in the passive layer growth over steel rebar surface immersed in an alkaline media simulating the concrete pore solution.

TL;DR: In this paper, the electrochemical reactivities and structural properties of several nickel hydroxide powders were analyzed by X-ray diffraction, Raman spectroscopy and extended Xray absorption fine structure (EXAFS).
