Corrosion rate monitoring of deteriorated and repaired structures through on-site linear polarization measurements using surface or embedded sensors

A linear polarization method was applied to measure corrosion rate of reinforced steel in concrete. The relationship between corrosion rate and mineral admixtures was discussed. The results show that changes of mineral admixtures material will affect the corrosion rate of reinforcing steel in concrete, of which slag is the most obvious.

Corrosion Susceptibility

The Tafel extrapolation and linear polarization methods were used as effective measures for determining the corrosion susceptibility of a spheroidized 0.35%C steel with sea water as the electrolyte. Eight pieces of steel were machined to length 5mm by 10mm in diameter. Two pieces each were heat treated at 600°C, 700°C and 800°C respectively and two pieces left as control. Electro-chemical experiments were carried out to obtain the best potential and anodic current of samples immersed in an electrolyte (seawater) at varying anodic potential of-0.7mv, -0.6mv, -0.5mv and-0.4mv respectively. The results showed that the sample with the least corrosion rate were the samples spheroidized at 700°C. They appeared to have the highest electrode potential value of-0.6mv and 800°C spheroidized samples had the least electrode potential value of-0.65mv at the end of 2000seconds respectively. From the results obtained, the samples spheroidized at 700°C appeared to be most suitable for seawater environment.
