Visualisation of the Electrical Resistivity Distribution of Reinforced Concrete
The electrical resistivity of concrete is a characteristic property correlating with different durability related parameters, e.g. the degree of water saturation, the corrosion rate of the reinforcement or the chloride diffusion coefficient. On structures the resistivity can be determined non-destructively by using a Wenner setup. The analysis is based on the assumption of a homogeneous semi-infinite concrete element. Based on the heterogeneous structure of reinforced concrete (e.g. reinforcement bars, moisture differences) the electrical field is deformed which may lead to misinterpretations.
To take these influences into account the application of the Electrical Resistivity Tomography (ERT) on reinforced concrete is studied. The method is based on several measurements with different electrode arrangements and distances in order to determine the true resistivity distribution in the concrete. The aim of the application is to identify local heterogeneities in order to quantify the resistivity distribution in concrete accurately.
