Chlorine ions,being an important factor affecting the durability of concrete,has attracted concern of many scholars in the civil engineering field both at home and abroad and becomes especially conspicuous in coastal marine works.There are now many methods to determine the penetration of chlorine ions in concrete,but there are great discrepancies in the measured parameters and results of evaluation.Adequate scope and conditions of application are proposed on the basis of the various testing methods and the characteristics of the testing methods for determining the penetration of chlorine ions in concrete as well as on the basis of the analysis and comparisons of the relative merits of these methods in order to ensure the scientificalness and reliability of the measured results and truly reflect the influence of the penetration of chlorine ions in structures,which may be of reference for the professionals in the same field.
