| Abstract: | The chloride diffusivity of cement based materials is correlated to the durability. Recent studies on the chloride diffusivity of cement-based materials by AC impedance spectroscopy as a novel research technique were reviewed. This technique can be classified into several aspects for analysis according to different test frequency ranges and principles. The investigated aspects include the layout of specimen and electrode, the validity test of experimental data, the equivalent circuit selection and the interpretation of the various parameters as well. The advantages and disadvantages of this technique were summarized. A future research scope was also proposed. |
