Hydro-mechanichal characterisation of bentonite/steel interfaces
Alessio Ferrari, Eleni Stavropoulou, Fabiana Sannasardo
The hydromechanical response of a Wyoming-type bentonite (MX-80) and its interface with steel was studied in terms of shear resistance under different hydration levels. A series of shear tests under constant normal stress were performed in total suction co ...
2023Shear strength and shear stiffness analysis of compacted Wyoming-type bentonite
Wyoming-type bentonite is one of the materials to be used as part of the Engineered Barrier System (EBS) in deep geological disposal facilities for the safe disposal of spent nuclear fuel.In the KBS-3 type repository, the canisters containing the spent fue ...
ELSEVIER2023Role of Stress History on the Swelling-Shrinkage Behavior of Compacted Scaly Clay
Compacted scaly clays are complex geomaterials widely used for the realization of dam cores and waste dump liners. This research aims to investigate the swelling/shrinkage behavior of these geomaterials subjected in an oedometric cell to complex hydromecha ...
ASCE-AMER SOC CIVIL ENGINEERS2022Studies on the mechanical evolution of compacted bentonite subjected to environmental actions
Deep geological disposal is currently the most feasible option for the long-term isolation of radioactive waste, consisting in emplacing the waste into tunnels or drifts excavated at great depths in suitable geological formations. The use of bentonite, a h ...
EPFL2021A 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 ...
EDP SCIENCES2020Basic creep and autogenous shrinkage of Limestone Calcined Clay Cement (LC3)
The use of supplementary cementitious materials (SCM) to lower the clinker factor of cements is now commonplace, for it benefits performance, economics and ecology. This thesis focuses on ternary blends of limestone and calcined kaolinitic clays, two very ...
