- •
Experimental approach evidencing mass transfer processes occurring in the EBS of a DGR at the repository conditions at mid-long term.
- •
The potential capacity of concrete and iron corrosion products interfaces to act as a sink of soluble salts were investigated.
- •
The role of exchangeable Mg buffering capacity regarding the neutralization of the alkaline plume in the EBS system was established.
- •
A low porosity bentonite-cement mortar zone was created: consequences in decreasing the hydration rate of the bentonite could be significant.
- •
The availability for exchangeable K+ uptake from cementitious materials affects initially the bentonite hydration and swelling.
