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 …

The interactions between cementitious materials and a clayey deep formation were
investigated by studying the specific in situ context of the Tournemire Underground …

Several repository concepts have been proposed for the disposal of radioactive wastes,
some of which include argillaceous (clay-rich) host rocks and cementitious engineered …

In the post-closure period of a geological disposal facility for radioactive waste, leaching of
cement components is likely to give rise to an alkaline plume which will be in chemical …

Interactions between concrete and clays are driven by the strong chemical gradients in pore
water and involve mineral reactions in both materials. In the context of a radioactive waste …

Mineralogical and petrographical investigations of a borehole sealed by concrete
(“engineered analogue” of concrete/clay interactions) overcored at the Tournemire site offer …

The safety of a geological repository designed for deep storage of nuclear waste rests on the
long-lived isolation properties of the geological environment and the engineered barrier …

The design of engineered barrier systems for high-level radioactive waste isolation requires
the use of cement-based materials. Small-scale surface reactivity interface experiments …

The results of in situ tests conducted at the HADES underground laboratory, Mol, Belgium,
indicate significant reaction between Boom Clay and ordinary Portland cement over a period …

Radioactive wastes in future underground disposal sites will induce a temperature increase
at the interface between the cementitious materials and the host rock. To understand the …
