The Le Chatelier awards were introduced to recognize outstanding research papers published in Cement and Concrete Research. Three research papers are awarded the distinction of being a Le Chatelier distinguished paper annually. This award is for our work on the Irish defective concrete crisis that our team first published in "The ‘mica crisis’ in Donegal, Ireland – A case of internal sulfate attack?" published in Cement and Concrete Research, Volume 168, June 2023.
