CR Behaviour of Fully and Partially Brine Saturated Building Stones and FE Modelling of Microstructural Features

In order to assign the value of complex resistivity measurements to non-destructively infer salt and water damages of building stones an experiment series has been conducted on brine saturated samples varying in type, fluid concentration and water content. CR parameter are evaluated and compared to previous results by other authors. A new image based FE modelling approach has been started to discriminate chemical from microstructural implications on CR spectra.
