Coupled hydro-mechanical analysis of compacted bentonite behaviour during hydration

Lyesse Laloui, Alessio Ferrari, Jose Antonio Bosch Llufriu

This study analyses the response of compacted bentonites upon hydration based on a coupled hydro-mechanical elasto-plastic framework. As an alternative to multi-porosity interpretation, the framework was selected based on the experimental evidence of adsor ...

A numerical study on the coupled hydro-mechanical behaviour of compacted bentonite

Lyesse Laloui, Alessio Ferrari, Jose Antonio Bosch Llufriu

Understanding the mechanical behaviour of compacted bentonite upon re-saturation is of outmost importance in most designs of nuclear waste disposal repositories. The behaviour of bentonite is characterized by its stress-path dependency and it is typically ...

A coupled hydro – mechanical approach for modelling the volume change behaviour of compacted bentonite

Lyesse Laloui, Alessio Ferrari, Jose Antonio Bosch Llufriu

The volumetric response of compacted bentonites against environmental actions is a key aspect in most designs of nuclear waste repositories. The safety assessment of such repositories must account for robust and reliable models of stress–strain for bentoni ...

The influence of different hydro-mechanical paths on final properties of saturated MX80 bentonite samples

Lyesse Laloui, Alessio Ferrari, Patrycja Ewelina Baryla

Compacted bentonite is considered to be used for deep geological nuclear waste disposal due to its isolation properties such as low permeability, solute retention and swelling pressure. To ensure that these properties will remain favourable throughout the ...

Hydro-mechanical analysis of gas transport in compacted bentonite: uncertainty modelling

Lyesse Laloui, Aldo Madaschi

In the last years, transport of gases in clay buffer materials for Engineered Barrier Systems (EBS) has been deeply investigated by many research programs in the framework of nuclear waste storage. At present state, the coupled hydromechanical models to an ...

A water retention model for compacted bentonites

Anne-Catherine Adolphine M Dieudonné

The water retention behaviour of compacted bentonites is strongly affected by multi-physical and multi-scale processes taking place in these materials. Experimental data have evidenced major effects of the material dry density, the imposed volume constrain ...

Water retention behaviour of compacted bentonites: experimental observations and constitutive model

Anne-Catherine Adolphine M Dieudonné

Bentonite-based materials are studied as potential barriers for the geological disposal of radioactive waste. In this context, the hydro-mechanical behaviour of the engineered barrier is first characterized by free swelling conditions followed by constant ...

The Pore Structure Of Compacted And Partly Saturated Mx-80 Bentonite At Different Dry Densities

Alessio Ferrari, Ali Seiphoori

Compacted MX-80 bentonite is a potential backfill material in radioactive-waste repositories. Pore space in MX-80 has been the subject of considerable debate. 3D reconstructions of the pore space based on tomographic methods could provide new insights into ...
