Pitting corrosion of reinforcing steel bars in chloride contaminated concrete
Highlights Corrosion of reinforcing steel bars in chloride contaminated concrete is investigated experimentally. Pitting corrosion of 50 corroded steel bars were analysed using statistical analysis methods. Probability distributions of pit depth, residual cross-section area and second moments of area are discussed. Correlations between pit depth, residual cross-section area and smaller principal second moments of area are examined.
Abstract This paper experimentally investigates the pit corrosion of steel bars in chloride contaminated concrete. The obtained 3-D images of the corroded bars are analyzed using statistical methods. The results show that the pit depth, residual cross-section area and smaller principal moment of inertia of plane area have multiple probability distribution patterns. The correlation of the pit depth with the mass loss is weak. The statistically obtained locations where the minimum residual cross-section area and minimum smaller principal moment of inertia of plane area are located are found to be close, suggesting this is the weakest section where the corroded bar will likely fail.
