Microstructural modelling of the elastic properties of tricalcium silicate pastes at early ages

Karen Scrivener, Shashank Bishnoi, Quang Huy Do

This paper describes the numerical calculation of elastic properties of a simulated microstructure of cement paste from very early age, when most previous models fail to give accurate results. The development of elastic properties of tricalcium silicate pa ...

Evolution of pore structure in blended systems

Karen Scrivener, Elise Marie Jeanne Berodier

In this study, the effect of SCM in the cement paste was isolated by using ternary systems combining Portland cement, quartz and SCM. The results show clear differences in how the hydrates from the reaction of clinker, slag and fly ash fill space. The reac ...

The influence of sodium salts and gypsum on alite hydration

Karen Scrivener, Berta Mota Gassó, Thomas Matschei

This work aims to clarify the impact of alkali and sulfate on the hydration kinetics and microstructural development of alite. The plain alite system is compared to systems with addition of: i) gypsum, ii) Na2SO4, iii) NaOH plus gypsum and iv) NaOH. In all ...

Fly ash as an assemblage of model Ca-Mg-Na-aluminosilicate glasses

Karen Scrivener, Ruben Anton Snellings, Cyrille Dunant, Mohsen Ben Haha, Pawel Tadeusz Durdzinski

Model Ca-Mg-Na-aluminosilicate glasses based on compositions found in a calcareous fly ash were synthesised and their reactivity assessed in NaOH solution and in Portland cement paste. It was found that the reactivity followed the same trend in both system ...

Influence of visco-elasticity on the stress development induced by alkali-silica reaction

Karen Scrivener, Cyrille Dunant, Alain Benjamin Giorla

The alkali-silica reaction causes long-term degradation in the microstructure of affected concrete as well as macroscopic expansion. In this paper, a micro-mechanical model based upon an explicit representation of the microstructure has been used to simula ...

Composition, silicate anion structure and morphology of calcium silicate hydrates (C-S-H) synthesised by silica-lime reaction and by controlled hydration of tricalcium silicate (C3S)

Emmanuelle Boehm Courjault

The main product of Portland cement hydration is C-S-H. Despite constituting more than half of the volume of hydrated pastes and having an important role in strength development, very little is known about the factors that determine its morphology. To inve ...

Advances in understanding hydration of Portland cement

Karen Scrivener, Patrick Juilland

Progress in understanding hydration is summarized. Evidence supports the geochemistry dissolution theory as an explanation for the induction period, in preference to the inhibiting layer theory. The growth of C-S-H is the principal factor controlling the m ...

Influence of silica fume on the microstructure of cement pastes: New insights from H-1 NMR relaxometry

Karen Scrivener, Arnaud Charles Albert Muller

H-1 NMR has been used to characterise white Portland cement paste incorporating 10 wt.% of silica fume. Samples were measured sealed throughout the hydration without sample drying. Paste compositions and C-S-H characteristics are calculated based on H-1 NM ...
