Abstract

For determination the electrolytic resistivity of concrete, resistances of realistic designed probes are measured during a one and two year period, respectively. Measurements are made with a commercially available instrument normally used for measuring earth resistances. Comparison to other usually applied methods show not only that the used method GEOHM is qualified for measuring the electrolytic resistance of concrete but also that the magnitude of measured values is realistic. To obtain electrolytic resistivities from these measurements the individual cell constant for the investigated system was derived from experimental research. First results of the in‐situ stored specimens are presented, intended future activities are sketched.

## Abstract Potential mapping is a widely applied and accepted non‐destructive measuring technique to assess the condition of concrete structures with respect to corrosion of the embedded reinforcement steel. Most often a single reference electrode is used to perform point measurements according to
