This paper presents an experimental investigation into the residual strength and mechanical properties of corroded reinforcing bare bars.
An attempt has been made to describe firstly the impressed current technique which is commonly used for accelerating reinforcement corrosion.
The study compared between two methods of repairing the corroded steel bar, the first one which mostly used by painting the half surface area of corroded bar; and the another one by coating the full surface area of corroded bar.
The experimental results show that, the corrosion process alters the external surface of steel bar due to pitting, the residual cross-section of the corroded bar is no longer round and varies considerably along its circumference and its length so the residual diameter is better defined by loss of weight.
The rate of corrosion has been calculated by two terms, the term of mass loss rate (MR) and the term of penetration rate (CR).
The mass loss rate decreased for fully coated bars by 1.7–2 times than half coated bars showing the importance of fully coating bars in corrosion repair.
Finally, the reliability of using the galvanostatic method in research work was represented by comparing between the real time and the accelerated time to reach a certain degree of corrosion.
