In this manuscript, electrochemical impedance spectroscopy (EIS) is induced as a nondestructive testing for understanding Cl-erosion in the cementitious materials.A new equivalent circuit model has been established to explain the Cl-eroding behavior.The reliability of the model has been proved by the experimental results.In order to explore the impact factors on the ions erosion, different experimental conditions are designed and studied, including ions concentration, eroding time, water/cement ratio of cementitious materials, dosage of fly ash, and so on.The eroding behavior is studied by experimental measurement and analyzed by the parameters fitted from the electrochemical model based on EIS.
