As the fastest growing energy sector globally, shale and shale reservoirs have attracted the
attention of both industry and scholars. However, the strong heterogeneity at different scales …

The buffer/backfill material of bentonite acts the most important role for the safety of high-
level nuclear waste repository. After the closure of repository, the concrete as another barrier …

This article summarizes long-term degradation mechanisms of cementitious materials in
contact with fresh and saline solutions based on a review of experimental observations in …

In the framework of the CI project, the interaction of two different low-pH cements (ESDRED
and LAC) with Opalinus Clay (OPA) at Mont-Terri rock laboratory was studied. SEM-EDS …

A specific oedometer cell has been set up to measure the swelling pressure of compacted
montmorillonites at constant volume and to concomitantly visualise the evolution, upon …

Interactions between cementitious materials and claystone are driven by chemical gradients
in pore water and might lead to mineralogical modifications in both materials. In the context …

Durability of concrete exposed to an external sulfate attack is a great concern for the long-
term reliability of nuclear waste containment. This paper presents experimental results …

In clay-rich sedimentary rocks, the pore network is considered to play a key role in
controlling transport properties. The pore size distribution (PSD) of clay-rich rocks, the …

In Switzerland, deep geological storage in clay rich host rocks is the preferred option for low-
and intermediate-level radioactive waste. For these waste types cementitious materials are …

Abstract The Cement–Opalinus Clay Interaction (CI) Experiment at the Mont Terri rock
laboratory is a long-term passive diffusion–reaction experiment between contrasting …
