T1 - On-site investigations on concrete resistivity – a parameter of durability calculation of reinforced concrete structures JF - Materials and Corrosion N2 - 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.
