Crystallization of hydrated and anhydrous salts in porous limestone resolved by synchrotron X-ray microtomography [PDF]
, 2014 ACLInternational audienceThe crystallization processes of two anhydrous salts (NaCl and Na 2SO4) and one hydrated (sodium sulfate) salt in the pore space of a natural building stone, Savonnières limestone, are studied.

Damage in porous media due to salt crystallization [PDF]
, 2010 We investigate the origins of salt damage in sandstones for the two most common salts: sodium chloride and sulfate. The results show that the observed difference in damage between the two salts is directly related to the kinetics of crystallization and ...

Interpreting Measurements of Small Strain Elastic Shear Modulus under Unsaturated Conditions [PDF]
, 2016 Bender element testing of unsaturated isotropically compacted speswhite kaolin samples was used to investigate the variation of small strain elastic shear modulus G under unsaturated conditions. Testing was performed in a suction-controlled triaxial cell

Giant osmotic pressure in the forced wetting of hydrophobic nanopores [PDF]
, 2015 The forced intrusion of water in hydrophobic nanoporous pulverulent material is of interest for quick storage of energy. With nanometric pores the energy storage capacity is controlled by interfacial phenomena.

Evolving fracture patterns: columnar joints, mud cracks, and polygonal terrain [PDF]
, 2013 When cracks form in a thin contracting layer, they sequentially break the layer into smaller and smaller pieces. A rectilinear crack pattern encodes information about the order of crack formation, as later cracks tend to intersect with earlier cracks at ...

Influence of Dry-Wet Cycles on the Structure and Shear Strength of Loess
Sustainability, 2023 The dry-wet cycle is an important factor that causes slope instability and foundation settlement in loess regions. In order to study the effects of the dry-wet cycle on the structure and shear strength of loess, isotropic compression tests and triaxial shear tests were carried out on loess with different numbers of dry-wet cycles. The results show that
