A three dimensional analysis of a drying test on a concrete-like material is presented. The analysis combines different tools, namely, X-ray microtomography of an ex situ experiment, image acquisition and processing, volume correlation to measure three dimensional displacement fields. It allows in particular mesoscopic strain analyses to be performed. By studying the correlation residuals, it is also possible to study the damage mechanisms.
