The superstructure of C3S from synchrotron and neutron powder diffraction and its role in quantitative phase analyses
TL;DR: In this article, the room temperature MIII form of alite stabilised by doping with Mg and Al was synthesized and the complex disordered superstructure of this tricalcium silicate [Ca3SiO5 (C3S)] sample has been studied by a joint Rietveld refinement of ultra-high-resolution synchrotron X-ray powder diffraction data, medium-resolution neutron powder diffusion data and soft constraints of interatomic distances.

Impact of Chemical Impurities on the Crystalline Cement Clinker Phases Determined by Atomistic Simulations
Hegoi Manzano,Engin Durgun,Mohammad Javad Abdolhosseini Qomi,Franz-Josef Ulm,Roland J.-M. Pellenq,Jeffrey C. Grossman +5 more
TL;DR: In this paper, a combination of classical and quantum mechanical simulation methods was used to study the detailed physicochemical changes of the clinker phases alite (Ca3SiO5) and belite(Ca2SiO4) when Mg2+, Al3+ and Fe3+ guest ions were incorporated into their structure.

Quantification of calcium silicate phases in Portland cements by 29Si MAS NMR spectroscopy
TL;DR: Inversion-recovery 29Si spin-lattice relaxation MAS NMR allows quantification of the relative content of alite and belite in an independent way and the results of the deconvolution for two of the cements have been tested and confirmed using this technique as mentioned in this paper.

The influence of the alite polymorphism on the strength of the Portland cement
Theodor Staněk,Petr Sulovský +1 more
TL;DR: In this paper, the influence of the alite polymorphism on the strength of cement was monitored in a set of laboratory-prepared clinkers with equal quantitative phase composition and different ratio of modifications.

Microscopic study on the polymorphism of Ca3SiO5
Iwao Maki,Stanislav Chromý +1 more
TL;DR: The polymorphism of Ca3SiO5 has been studied microscopically by following changes in optic properties and modes of twinning of the crystal as a function of temperature.

Portland cement clinker mineralogical and chemical investigations: Part II electron microprobe analysis
TL;DR: In this paper, the chemistry of the clinker minerals was studied with the electron microprobe; the alites and belites could be easily determined but the aluminates and ferrites were difficult or impossible to determine separately.
