Corrosion of reinforcing steel in concrete is a serious problem from the point of view of both safety and economy. Therefore, it is essential to have reliable measurement techniques to evaluate the corrosion condition of the steel bars in the reinforcing concrete. Electrochemical assessment of the condition of the steel reinforced concrete structures is being carried out increasingly and more regularly, both in the laboratory and in the field. It is important to have enough information about the factors that may affect these measurements. In this way, results obtained from ...
