An electrochemical method for accelerated testing of chloride diffusivity in concrete

Influence of cation type on diffusion behavior of chloride ions in concrete

“…Thus, in this paper, the apparent diffusion coefficients of chloride ions combined with divalent cations are found greater than those combined with monovalent cations. In fact, the same trend has appeared in the previous workers' investigation [13] although the correct analysis was not given. Certainly, the bound rate is not the only factor influencing the apparent diffusion coefficient.…”

Microstructure-Based Prediction Model for Chloride Ion Diffusivity in Hydrated Cement Paste

“…When the change of chloride ion diffusion in cell 2 is in a steady state, the chloride ion diffusion coefficient (m 2 /s) of the specimens is calculated via Equation 8 [22].…”

New method development for evaluation concrete chloride ion permeability

“…Therefore, in Norway a similar method was introduced, where the so-called ''Chloride Permeability'' was based on the observed rate of chloride migration through the concrete [16]. Since the beginning of the 1980's, this method has been widely used in Norway for general quality assessment of concrete durability [17]. Since Chloride Permeability is heavily dependent on the particular testing conditions used, it is also an empirical quality parameter.…”
