Deterioration of reinforced concrete structures caused by chloride-induced corrosion is one of the main problems for
durability in reinforced concrete structures. Recent researches demonstrate that position and size of anodic and cathodic
angles have strong influence on crack pattern and corrosion rate and the anodic-cathodic ratios have influence on
corrosion-induced damage. All previous researches considered studying the influence of different anodic angles
numerically but no experimental investigations were found. In this paper, the influence of different anodic angles on
corrosion crack pattern and corrosion rate is investigated experimentally by applying accelerated corrosion test using
impressed voltage technique to centrally reinforced concrete cylinders with different anodic angles (360°, 180° and
60°). Current-Time relationship, percentage of steel mass loss and bond strength of the corroded samples are discussed.
The results show that the different anodic angles have strong influence on the corrosion crack pattern, corrosion rate
and bond strength. Also, it is demonstrated that the developed experimental techniques in this study can be used to
investigate the influence of different anodic angles.
