Thermo-mechanical behaviour of a compacted swelling clay [PDF]
, 2008 Compacted unsaturated swelling clay is often considered as a possible buffer material for deep nuclear waste disposal. An isotropic cell permitting simultaneous control of suction, temperature and pressure was used to study the thermo-mechanical ...

Deep Underground Science and Engineering, EarlyView.The tensile strength of granite, a proposed host for nuclear waste, degrades severely above 400°C. We link this to specific microcracking patterns captured by acoustic emission, establishing a scientific basis for assessing repository safety under thermal load.

Activated Bentonite for Physical, Mechanical, and Durability Properties of Concrete—A Review
Advances in Civil EngineeringBentonite mostly exists in many counties and studies reported employment of activated bentonite in the concrete improves concrete performance more than using raw bentonite. However, it is not well-known which range of bentonite activation temperature and

Molecular Insights Into the Water Freezing on Kaolinite Surfaces: The Key Role of Surface Properties
International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT Unfrozen water content is a key factor governing the physical properties of frozen soils, and variations in mineral surface properties play a critical role in determining this content. However, the fundamental physical mechanisms of how different mineral surfaces affect soil water freezing remain poorly understood.
