Engineering Solutions Electrochemical analysis system for measuring corrosion potential and rate Overview Corrosion of steel reinforcement inside concrete reduces the effective cross-sectional area of the steel bar and leads to an increase in volume. This expansion causes cracking and spalling of the concrete element, reducing its mechanical properties and durability, and consequently compromising the safety of the affected structures. The detection of the corrosion level of steel bars in concrete elements is therefore one of the fundamental parameters to consider in the identification of the degradation state and in the assessment of the safety of the structure under examination.
