Parameters That Influence Corrosion Detection in Reinforced Concrete Based on Eddy Current Thermography

Figure 4

(a) The surface temperature depends on time for specimens with different depths of the concrete cover, and (b)–(d) the rate of the temperature rise dependence on the corrosion time for specimens with different diameters of the internal steel bar and with different concrete cover depths.
