Bentonite analysis

The objective of this work is to determine the mechanical, hydraulic, and geochemical characteristics of the bentonite blocks from different parts of the buffer including the joints and validate model predictions when variations in the material properties have been defined.

The work in this task includes laboratory tests on samples taken during the dismantling operation. The following parameters have been determined:
- Water content and bulk density,
- Permeability,
- Geotechnical (i.e. thermal, swelling, strength, and deformation), geochemical, and mineralogical alteration,
- Pore water chemistry alteration,
- Effects of corrosion products.

With these results, we quantify and spatially define the progression of the geochemical, textural, micro/macro structural transformation in the buffer.
