Elektrochemische, zerstörungsfreie Prüfmethoden für Zustandsanalysen und Qualitätssicherung bei Instandsetzung von Stahlbetonbauten / Electrochemical non-destructive test methods for the assessment and quality control of restoration measures of reinforced concrete structures

In this state of the art report the electrochemical, non destructive techniques for the survey, assessment and the quality control of reinforced concrete structures such as the potential mapping, the measuring of concrete resistivity and the polarisation resistance for on-site applications are described. Along with a short description of each technique especially those aspects are discussed, that are important for on-site applications: possibilities and limits of the technique as well its suitability for use in the different stages of rehabilitation works. The examples from practical on-site applications will be presented in a following report.
