Abstract
A unique self-compacting concrete was developed for use
in long-term nuclear waste repository tunnel end plugs.
For stability of bentonite clay in the repository for
thousands of years, the pH of the concrete leachate is
required to be below 11. Two applicable mix designs were
developed. A final mix design having a ternary binder
composition was selected to be use in a full-scale
demonstration tunnel end plug at 450 metres underground.
Successful demonstration was performed after adjusting
the mix design to fulfil the requirements of a batching
plant production.
