Sandstone is an important cultural heritage material, in both architectural and natural settings, such as neolithic rock art panels. The majority of deterioration effects in porous materials such as sandstone are influenced by the presence and movement of water through the material. The presence of water within the porous network of a material results in changes in the optical coherence tomography signal intensity that can be used to monitor the wetting front of water penetration of dry porous…

Fracture of a model cohesive granular material.
TLDR
The fracture mechanisms of a model cohesive granular medium consisting of glass beads held together by solidified polymer bridges are studied, showing that its fracture toughness can be tuned over an order of magnitude by adjusting the stiffness and size of the polymer bridges.
