Water retention behaviour and microstructural evolution of MX-80 granular bentonite during wetting and drying cycles

Lyesse Laloui, Alessio Ferrari, Ali Seiphoori

MX-80 bentonite used in engineered barrier systems would be subjected to wetting and drying cycles. To assess the response of the material under such circumstances, a comprehensive experimental characterisation of the water retention behaviour of compacted ...

Yield stress modelling of doped alumina suspensions for applications in freeze granulation: towards dry pressed transparent ceramics

Paul Bowen, Michael Stuer

Rheology of powder suspensions is a key factor in many processing routes, and better understanding of the parameters that control the rheology improves technical progress by reducing the empirical factors in the formulation of powder slurries. The strict r ...

Benchmark of experimental techniques for measuring and controlling suction

Lyesse Laloui, Hervé Péron

The paper presents a benchmarking study carried out within the ‘Mechanics of Unsaturated Soils for Engineering’ (MUSE) network aimed at comparing different techniques for measurement and control of suction. Techniques tested by the eight ‘Mechanics of Unsa ...

New Fe-immobilized natural bentonite plate used as photo-Fenton catalyst for organic pollutant degradation

César Pulgarin

Novel photo-Fenton catalysts were prepared by immobilizing iron species on commercial bentonite plates via two methods: (1) ion exchange reaction (Fe3+ vs. Na+) by aqueous suspension powder-clay/FeCl3 followed by plate preparation, and (2) forced hydrolysi ...

Effect of temperature on collapse potential of kaolin clay

Lyesse Laloui

The understanding of the fundamental behaviour of clays subjected to high temperatures is essential when working with clay barriers in nuclear waste storage, drilling of deep offshore wells or using clay liners on landfills. The effect of temperature on th ...

Release kinetics of volatiles from smectite clay minerals

Pascal Clausen

The focus of this thesis was on the mechanisms of release of volatile molecules from smectite clay minerals. The weight loss was monitored by thermogravimetry, differential calorimetry, and mass spectrometry under isothermal conditions and under ramp tempe ...
