The corrosion of the steel inside the concrete reduces the effective area of the steel bar section and leads to an increase in volume. This expansion involves a demolition of the concrete element, reducing the mechanical characteristics and durability of the material, and consequently the safety of the structures involved.
The detection of the degree of corrosion of the steel bars in the concrete elements is, therefore, one of the fundamental parameters to be considered in identifying the state of degradation and in assessing the safety of the examined structure.
The NOVASCAN C310A electrochemical analysis system for the measurement of corrosion potential and rate uses the theory of electrode polarization; is designed according to the electrochemical test method (natural potential method), in accordance with the requirements of the regulations on the assessment of structural integrity.
• High detection accuracy: the corrosion voltage detection accuracy is +/- 0.1 mV;
• The test results are displayed in a hierarchical graphic: the degree of corrosion is shown in a hierarchical graphic, corresponding to the range of electrodes;
• Two working modes: single and double electrode
