Exploration of the X-ray Dark-Field Signal in Mineral Building Materials [PDF]
Journal of Imaging, 2022 Mineral building materials suffer from weathering processes such as salt efflorescence, freeze–thaw cycling, and microbial colonization. All of these processes are linked to water (liquid and vapor) in the pore space. The degree of damage following these
