Preparation and characterization of alkali-activated white belite cements
Materiales de Construccion, 2009 Activated white cement clinkers with a theoretical 60% (wt) belite (dicalcium silicate) content were prepared at a temperature 100 ºC lower than used to manufacture conventional white Portland cement clinkers.

Multiscale understanding of tricalcium silicate hydration reactions [PDF]
, 2017 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 Rietveld Method ? A Historical Perspective [PDF]
Australian Journal of Physics, 1988 differences between observed and calculated values was already well established in crystallography. From there it was, in retrospect, only a small step to refrain from using the integrated intensities as observed values but to use the actual measured profile intensities obtained by step scanning the powder diagram.
