Physico-mechanical investigations on mineralogical clay-based ceramic bodies with rock residue

Mechanical interaction between swelling compacted clay and fractured rock, and the leaching of clay colloids

We consider the interaction between a saturated clay buffer layer and a fractured crystalline rock engineered disturbed zone. Once saturated, the clay extrudes into the available rock fractures, behaving as a compressible nonNewtonian fluid. We discuss the modelling implications of published experiments carried out in Sweden and more recently in Japan. Extrusion is halted either when the advanc...

Investigations of Near-field Thermal-hydrologic- Mechanical-chemical Models for Radioactive Waste Disposal in Clay/shale Rock

Effect of Natural Fibres Inclusion in Clay Bricks: Physico-Mechanical Properties

In spite of the advent of new materials, clay bricks remain, arguably, the most popular construction materials today. Nevertheless the low cost and versatility of clay bricks cannot always be associated with high environmental and sustainable values, especially in terms of raw material sources and manufacturing processes. At the same time, the worldwide agricultural footprint is fast growing, w...

New Coating Technique of Ceramic Implants with Different Glass Solder Matrices for Improved Osseointegration-Mechanical Investigations

Ceramics are a very popular material in dental implant technology due to their tribological properties, their biocompatibility and their esthetic appearance. However, their natural surface structure lacks the ability of proper osseointegration, which constitutes a crucial process for the stability and, thus, the functionality of a bone implant. We investigated the application of a glass solder ...

Clay-shoveler's fracture during indoor rock climbing.

Indoor rock climbing is becoming more popular for people of all ages. Despite the tremendous interest in this competitive sport, participants are made aware of the dangers associated with participating. The authors present the first reported case of a clay-shoveler's fracture at the T1 spinous process during indoor rock climbing. They describe the management and natural history of this fracture...
