Despite the constant development of new materials, reinforced concrete is still widely used in civil engineering. Corrosion of the steel armour in reinforced concrete structures has historically been one of the main causes of damage and early failure. The development of a reliable method of non-invasive corrosion inspection and evaluation has been a challenge for many years. This paper focused on magnetic inspection of the tendons in steel armours. Results show a good correlation between micromagnetic parameters and corrosion evolution, indicating that the method is a viable option for integrity monitoring of such structures.
