- This paper presents the first rigorous thermodynamic model for calcium-aluminosilicate hydrate gels, which form the basis of modern cements. This is a major advance in understanding and describing the chemistry of Portland cement and its blends with supplementary materials, as well as newly developed alkali-activated cements, which could not previously be incorporated into the geochemical-type models used in industry and academia to predict cement reactions and performance. Our model has since been deployed by the maintainers of the Swiss government-supported CEMDATA database https://www.empa.ch/web/s308/tutorials and was the topic of invited talks at the Goldschmidt2015 and Nanocem Spring 2016 conferences.
