Physical, chemical and biological weathering has a constant effect on the earth’s landscape. This also impacts our building infrastructure, as stone and masonry are damaged by a combination of different processes, such as chemical attack, biological colonization, water infiltration and changes in temperature. Fluid flow, reactive transport, nucleation, dissolution, precipitation and mass transport are crucial processes occurring inside the pore system of geomaterials.

To fully understand the macroscopical behaviour of geomaterials in this context, their pore scale properties and processes have to be understood. The stone’s mineralogy and pore structure strongly affect key internal pore scale processes. These processes have been studied indirectly by micro- and macroscopic observations and laboratory experiments. Although this provides valuable information, the key drivers of these processes are to be studied at the pore scale.

To explore these dynamic pore-scale processes, several non-destructive 3D and 4D methods are currently available. These tools provide additional important insights. Unravelling pore-scale processes in combination with pore scale modelling is an essential step towards understanding and predicting a geomaterial’s macroscopic behaviour correctly.

The presentation discusses the current possibilities and challenges in non-destructive pore-scale imaging of geomaterials and how this data can be used as input for fluid flow models and their validation. Additional new developments at the synchrotron and on lab-based X-ray systems related to material characterization as well as to the understanding of pore-scale processes are discussed. Examples will be given of different experiments related to the characterization and the imaging of dynamic pore scale processes in (geo)materials.
