15 years of in situ cement–argillite interaction from Tournemire URL: Characterisation of the multi-scale spatial heterogeneities of pore space evolution

S Gaboreau, D Prêt, E Tinseau, F Claret… - Applied …, 2011 - Elsevier
The solution selected by some countries to isolate radioactive wastes from the biosphere for
up to one million years in deep geological repositories includes a multi-barrier disposal
design, with steel canister, bentonite and cement materials. The geochemical contrast
between such materials and the host rock formation creates perturbations potentially altering
the confinement properties of the formation. In this context, the French Institute for the
Radiological protection and Nuclear Safety (IRSN) have developed an in situ experimental …
