TY - CONF A1 - Ebell, Gino T1 - Potential Mapping - What could we measure and what should we able to detect – guideline B03 of DGZfP N2 - “Electrochemical potential mapping according to guideline B3 of DGZfP (German Society for Non-Destructive Testing) is a recognized technique for the localization of corroding reinforcing steels. Areas of corroding reinforcement steel can be located in a non-destructive manner by means of this procedure. Half‐cell potential measurements are used in order to detect chloride‐induced corrosion. However, it is not recommended in order to assess the risk of carbonation‐induced corrosion. For this purpose, determining the carbonation depth and the concrete cover appears more appropriate. The content of this specification exclusively refers to the application of mobile, local variable reference electrodes, which are only placed on the concrete surface while measuring. The technique distinguishes itself thereby from the range of corrosion monitoring systems with stationary installed reference electrodes and sensor systems, respectively, whereby it is possible to continuously track measurements within the area of the installed electrodes. However, these methods are not dealt with in this specification.” T2 - NDT-CE 2022 CY - Zurich, Switzerland DA - 16.08.2022 KW - Korrosion KW - Potentialfeldmessung KW - Corrosion KW - Half-cell potential KW - Potential mapping PY - 2022 AN - OPUS4-55524 LA - eng AD - Bundesanstalt fuer Materialforschung und -pruefung (BAM), Berlin, Germany ER -
