Abstract

This paper reports an experimental work to investigate the pit corrosion of steel bars in chloride contaminated concrete. A total of 50 reinforcing steel bars with a length of 250 mm and a diameter of 14 mm were embedded in 10 concrete specimens, before they were subjected to accelerated corrosion. The geometric parameters of the corroded steel bars were then examined using 3D scanning method, before the characteristics of pitting corrosion of the corroded bars were analyzed accordingly. The results show that there is a weak correlation between the maximum pit depth and the mass loss rate. However, there is a strong correlation between the pitting factor and the mass loss rate. The relationship between the pitting factor and the mass loss rate has been developed as a reciprocal function.
