Calcium complexation and cluster formation as principal modes of action of polymers used as superplasticizer in cement systems
Journal ArticleDOI
Alite dissolution and C-S-H precipitation rates during hydration
TL;DR: In this paper, an extensive dataset suitable for kinetic calculations was collected for the hydration of monoclinic alite at water to solid ratios of 10 and 0.5, and reaction rates for the two kinetic steps alite dissolution and C-S-H precipitation were calculated from this dataset and compared to the measured reaction rates.
Journal ArticleDOI
Dissolution rates during the early hydration of tricalcium silicate
TL;DR: In this article, the authors investigated the hydration of triclinic tricalcium silicate containing foreign oxides using thermal analysis, pore solution analysis, and calorimetry.
Journal ArticleDOI

TL;DR: In this article, it was shown that as early as 2.5h after water addition at approx. 30°C, small amounts of Calcium Silicate Hydrate (C-S-H) form which may contribute to a bridging of the cement particles.
Journal ArticleDOI
Analysis of the surface of tricalcium silicate during the induction period by X-ray photoelectron spectroscopy
TL;DR: In this paper, X-ray photoelectron spectroscopy was applied to the hydration of tricalcium silicate (Ca 3 SiO 5, C 3 S) by analyzing a sample after 30min of hydration.
