One of the main factors of premature deterioration of concrete structures is the corrosion of reinforcements. Chloride penetration of concrete is one of the main reasons of this phenomenon. Therefore, to have durable structure, it is necessary to have concretes with low permeability.There are various methods to evaluate permeability of concrete. Finding a relationship between them can be useful for understanding the mechanism of corrosion. Concrete resistivity test is a suitable indicator for concrete penetration and chloride ion permeability. It is a non-destructive, simple, rapid and cheep method that can also be used in site.In this study, various permeability and resistivity tests were carried out on different types of concrete to find a relationship between them. In addition, the main factors affected the resistivity are disgusted and the major constraints of relation between resistivity and permeability of concrete are illustrated. Finally, a new method is recommended to eliminate these problems.
