Steel reinforcement

I would like to have some suggestions concerning any NDT method for the evaluation of the corrosion of the reinforcement bars of some concrete structures. Please take into account that, if needed, some portions of the concrete can be also demolished to expose directly the steel bars.
Thank you very much in advance and best wishes.

There is a method called electro-chemical potential measurement that allows a relatively quick survey be made for suspected corrosion areas. Only experienced persons should carry out such examinations since a number of parameters has influence on the results.

In Germany, e.g.

Baustoff- und Bodenprüfstelle Kassel
Mr. Dumat
Knorrstr. 32
D-34134 Kassel
Phone +49 (0561) 7286438

offers such analysis.

There are at least two standards on electro-chemical potential measurements:

1. Swiss standard:
Durchführung und Interpretation der Potentialmessung an Stahlbetonbauteilen.
Merkblatt 2006, Schweizerischer Ingenieur- und Architektenverein, Ausgabe 1993-02

2. U.S.-American standard:
Standard Test Method for Half-Cell Potentials of Uncoated Reinforcing Steel in Concrete.
ASTM, C876-91, 1991
