Abstract:
The linear polarization technique has been used in the laboratory for corrosion rate measurements of reinforcing bars in concrete, but some modifications are needed for its application to structures in the field. A new device has been developed, using this technique with a sensor-controlled guard ring to measure corrosion rates in concrete structures. Describes the performance of this device and its application. It also summarizes some results from reinforced concrete structures, including bridges, in Europe and the U.S.
