چکیده مقاله:
Corrosion of reinforced concrete structures is one of the major factors in creating intensive damages in concrete structures installed in south region of Iran. This phenomenon has been in the focus of many studies recently. Since during corrosion assessment stage there is a difference between results of accelerated and field tests, it is necessary to conduct field evaluation survey in this regard. In the current article corrosion behaviour of reinforced concrete cylinders, containing micro silica, corrosion inhibitors and without any additive were studied using Electrochemical Impedance Spectroscopy (EIS). The samples were exposed to corrosive environment in Northern margin of Persian Gulf in a corrosion research center for ۸ years. Analysis of observed spectra in terms of modified Randles circuit appeared to be a reasonable approximation. In addition micro silica added samples have ۱.۸ and ۱۳.۴ times better charge transfer resistance comparing to the corrosion inhibitor added and without any additive samples, respectively
