Micro Abstract:
In this contribution, we show examples of X-ray phase and dark-field contrast X-ray imaging, based on refraction and ultra-small angle scattering of the transmitted X-ray photons, respectively, as applied to cement-based materials during changes in their water content due to distinct processes. We overview what can be gained by using such imaging methods compared with what achievable with standard, attenuation contrast ones.
