Insights from an extensive triaxial testing campaign on a shale for comparative site characterization of a deep geological repository

Lyesse Laloui, Alessio Ferrari, Eleonora Crisci

Several boreholes were drilled for site comparison of a deep geological repository (DGR) in Northern Switzerland. The main target of the exploration program was the >100m thick Opalinus Clay, the designated host rock encountered at approximately 450 to 100 ...

Effect of the mineralogical composition on the elastoplastic hydromechanical response of Opalinus Clay shale

Lyesse Laloui, Alessio Ferrari, Eleonora Crisci

Opalinus Clay is the shale currently under investigation as the host formation for geological radioactive waste disposal in Switzerland. Its hydromechanical response has been widely studied, and the experimental results show a range of values whose dispers ...

Increasing the kaolinite content of raw clays using particle classification techniques for use as supplementary cementitious materials

Karen Scrivener, Franco Alberto Zunino Sommariva

The adoption of blended cements to reduce the carbon footprint has increased significantly over the last decades. Clays containing kaolinite are a promising choice due to their widespread availability. Kaolinite content is the major factor controlling the ...

Bentonite clay barriers in nuclear waste repositories

Lyesse Laloui, Alessio Ferrari, Jose Antonio Bosch Llufriu

Deep disposal of high-level radioactive waste is the preferred solution worldwide for the long-term disposal of nuclear waste. This concept involves a series of geological and engineered barriers that provide isolation of the waste from the biosphere. Most ...

Impacting factors and properties of limestone calcined clay cements (LC3)

Karen Scrivener, Franco Alberto Zunino Sommariva, François Henri Avet, Julien Ston, Aurélie Rosine Favier, Hamed Maraghechi, Wilasinee Hanpongpun

This paper details the main factors influencing the performance of limestone calcined clay cements (LC3). The kaolinite content plays a major role in the rheological properties as well as strength development. Even in the presence of secondary phases, kaol ...

Investigation of C-A-S-H composition, morphology and density in Limestone Calcined Clay Cement (LC3)

Karen Scrivener, Emmanuelle Boehm Courjault, François Henri Avet

In this study, the C-A-S-H composition, morphology and density are characterized for Limestone Calcined Clay Cement (LC3-50) blends containing clays with various kaolinite contents. Significant incorporation of aluminium is observed for LC3-50 blends compa ...

Hydro-mechanical behaviour of shallow Opalinus Clay shale

Lyesse Laloui, Alessio Ferrari, Eleonora Crisci

In Switzerland, Opalinus Clay shale has been selected as the host formation for radioactive waste disposal. The minimum required depth of the repository is related to the long-lasting isolation required for the disposal (1 million years). During this perio ...

Impact of Mineralogical Composition on Geotechnical Properties of Opalinus Clay

Lyesse Laloui, Alessio Ferrari, Eleonora Crisci

Opalinus Clay is the selected host geomaterial for the construction of underground geological disposals for radioactive waste in Switzerland. The formation has been studied in several sites, i.e. the Mont Terri laboratory, and several boreholes in the nort ...
