Abstract
This presentation describes research done within an EU
FP7 Euratom project, to develop and validate the
performance of low-pH concretes used in high level
radioactive nuclear waste containment structures. The
unique type of concrete is used for deposition tunnel end
plugs that are approximately 400 metres underground
within repository conditions. The research has focused on
producing highly workability mixtures with local
materials, where rheology and heat of hydration have been
optimized simultaneously with long-term durability and
watertightness targets. The results are being implemented
with full-scale construction of the 6 metre long tunnel
plug in the 15 m2 tunnel cross section.
