Non-Destructive Corrosion Rate Monitoring for reinforced Concrete Structures

The corrosion of reinforcements has resulted to be one of the most frequent causes of their premature failures. Monitoring the corrosion rate, assuming the uniform corrosion and the loss in diameter decreases linear with the corrosion rate, allows calculating the remaining load carrying and the safety of the structure. There are several methods of measuring true, instantaneous rate of corrosion, based on electrochemical methods. This paper describes electropotential mapping method and measuring techniques with the Gecor 6 device, their application, advantages and disadvantages based on our own experiences, and the interpretation of the measurement results.
