Zajac, M, Skocek, J, Adu-Amankwah, S et al. (2 more authors) (2018) Impact of microstructure on the performance of composite cements: Why higher total porosity can result in higher strength. Cement and Concrete Composites, 90. pp. 178-192. ISSN 0958-9465
Abstract
This paper describes the underlying principles behind the evolution in performance of ternary composite cements comprising Portland cement clinker, slag and limestone. By using the predicted phase assemblage as an input for the micromechanical model, the mechanisms underlying the evolution of mortar strength and Young's modulus were analyzed and quantified. This allowed the roles of hydrate assemblages and porosity distribution on the evolution of performance to be explained and quantified. Slag hydration results in the formation of a microstructure more efficient for development of compressive strength and elastic stiffness. Limestone further improves microstructure and enhances reactivity of the systems studied.
