Determining the corrosion of reinforcement is vital for construction safety. Seismic activity, lateral
displacements and sudden heat exchanges cause to consist microtension cracks in the reinforcement,
which increases reinforcement corrosion. Structures exposed earthquake load, especially bearing
elements, must resist distorsion. However, it is known that when there is a corrosive zone in the
reinforcement, the torsional rigidity weakens. Corrosion show up due to various physical factors. These
factors include acid and chemical gases. However, in this study, rusting, which is the oxidation reaction
of iron, was especially examined. The main factors that cause rusting are oxygen, moisture and leachate.
In this study, the reinforcement corrosion response was measured using non-destructive structural
geophysics techniques. For this purpose, standard C25 reinforced concrete was used. In experimental
studies; Ultrasonic velocity test measurements were performed with both Self Potential (S.P.) methods.
Accordingly, the oxidation zone in the model reinforcement gave an anomaly reaction with SP
measurements. This anomaly is the galvanic current effect caused by electrochemical ion exchange. In
ultrasonic tests, Vp and Vs wave velocities responded significantly in the oxidation zone
