Concrete mix designs for tunnel end plugs in nuclear waste repository

Research output: Chapter in Book/Report/Conference proceedingConference article in proceedingsScientificpeer-review

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.
