Salt weathering drastically reduces the durability of building stones. A thorough understanding of the coupled transport-crystallization-mechanics phenomena is therefore indispensable. Building on previous work in which neutron radiography was employed, we now focus on a more profound characterization of the micromechanics of crystallization-induced fracturing by DVC analysis of a 4D X-ray tomographic dataset.
