Stress release and suction generation in the Callovo-Oxfordian claystone

Investigating the Swelling Pressure of 1 Compacted Crushed - Callovo - Oxfordian Claystone

Oedometric compression and swelling behaviour of the Callovo-Oxfordian argillite

The Callovo-Oxfordian (COx) argillite is a possible host rock for radioactive waste disposal in which the ANDRA underground laboratory of Bure (East of France) has been excavated. In this paper some aspects of the volume change behaviour of the COx argillite are investigated. To do so, high pressure oedometers with a maximum capacity of 113 MPa have been used. In a first stage, swelling tests w...

Preferred Orientations and Anisotropy in Shales: Callovo-oxfordian Shale (france) and Opalinus Clay (switzerland)

Anisotropy in clay-rich sedimentary rocks is receiving increasing attention. Seismic anisotropy is essential in the prospecting for petroleum deposits. Anisotropy of diffusion has become relevant for environmental contaminants, including nuclear waste. In both cases, the orientation of component minerals is a critical ingredient and, largely because of small grain size and poor crystallinity, t...
