Show summary
Tricalcium silicate, the main constituent of Portland cement, hydrates to produce crystalline calcium
hydroxide and calcium-silicate-hydrates (C-S-H) nanocrystalline gel. This hydration reaction is poorly
understood at the nanoscale. The understanding of atomic arrangement in nanocrystalline phases is
intrinsically complicated and this challenge is exacerbated by the presence of additional crystalline
phase(s). Here, we use calorimetry and synchrotron X-ray powder diffraction to quantitatively follow
tricalcium silicate hydration process: i) its dissolution, ii) portlandite crystallization and iii) C-S-H
gel precipitation. Chiefly, synchrotron pair distribution function (PDF) allows to identify a defective
clinotobermorite, Ca11Si9O28(OH)2
.8.5H2O, as the nanocrystalline component of C-S-H. Furthermore,
PDF analysis also indicates that C-S-H gel contains monolayer calcium hydroxide which is stretched
as recently predicted by first principles calculations. These outcomes, plus additional laboratory
characterization, yielded a multiscale picture for C-S-H nanocomposite gel which explains the observed
densities and Ca/Si atomic ratios at the nano- and meso- scales.

Hydration of C4AF in the presence of other phases: A synchrotron X-ray powder diffraction study.

Show summary
Hydration behaviour of C4AF in selected experimental conditions has been determined. C4AF has been hydrated in the absence and presence of gypsum, two polymorphs of ye'elimite and different water/solid ratios. C4AF in the presence of water hydrates to form mainly a hydrogarnet-type phase. The crystal structure of C3A0.845F0.155H6 is reported from the Rietveld analysis of its synchrotron X-ray powder diffraction pattern. The hydration of C4AF in the presence of gypsum gives AFt. However, the mixture tetracalcium aluminoferrite/gypsum/ye'elimite gives both AFt and AFm phases. C4AF hydrated with ye'elimite in the absence of gypsum gives only AFm. Ye'elimite has inhibited tetracalcium aluminoferrite hydration.

Show summary
Eco-friendly belite calcium sulfoaluminate (BCSA) cement hydration behavior is not yet well understood. Here,
we report an in-situ synchrotron X-ray powder diffraction study for the first hours of hydration of BCSA cements.
Rietveld quantitative phase analysis has been used to establish the degree of reaction (α). The hydration of a
mixture of ye'elimite and gypsum revealed that ettringite formation (α ~70% at 50 h) is limited by ye'elimite
dissolution. Two laboratory-prepared BCSA cements were also studied: non-active-BCSA and active-BCSA cements,
with β- and α′H-belite as main phases, respectively. Ye'elimite, in the non-active-BCSA system, dissolves
at higher pace (α ~25% at 1 h) than in the active-BCSA one (α ~10% at 1 h),with differences in the crystallization
of ettringite (α ~30% and α ~5%, respectively). This behavior has strongly affected subsequent belite and ferrite reactivities, yielding stratlingite and other layered phases in non-active-BCSA. The dissolution and crystallization processes are reported and discussed in detail.
