Etude structurale et cristallographie des composés du ciment anhydre.

Abstract : This structural study on the anhydrous cement compounds primarily focused on the major component, the alite (tricalcium silicate impure), which hydration produced the largest fraction of the effect of hydrated cement paste. The tricalcium silicate C3S, this polymorphism depends on both temperature and the impurities it contains. The seven varieties of polymorphs are triclinic symmetry (forms called T1, T2, T3), monoclinic (M1, M2, M3) and rhombohedral (R). In the industrial clinkers, the bedridden are essentially stabilized symmetries monoclinic. The identification of this polymorph is hard diffraction X-rays because the powder patterns are very similar. Why do some impurities they stabilize one form over another? Is there a link between the observed structure and reactivity of the clinker? It must rely on a good structural knowledge of different polymorphs attempt to answer these questions.
