Solid solubility of MgO in the calcium silicates of portland clinker. The effect of CaF2

S. Martínez、F. Puertas、A. Palomo1992-03-01Materiales de Construccion

The solid solubility of MgO in the calcium silicates of portland clinker has been determined by XRD and XDS. The influence that the presence of CaF2 has on said solubility has also been verified. The solid solution limit of MgO in C3S at 1275 ºC lies at about 1.0% wt, where the triclinic form II stabilizes. The presen…

The effect of pozzolan additions on the shrinkage of cement pastes and mortars during their first hours of age

M. Mauricio Ossa、D. Jorge David1992-03-01Materiales de Construccion

The traditional favour enjoyed by cement including additions and by their diverse uses in Chile calls for an extense investigation of their behaviour in order that the results may justify their utilization in specific projects. This works studies volume changes occurring in cement pastes and mortars containing pozzola…

Generalized atomic displacements in crystallographic structure analysis

W. F. Kuhs1992-03-01Acta Crystallographica Section A Foundations of Crystallography

An attempt is made to summarize both theoretical and experimental aspects of generalized atomic displacement parameters (ADP's) in crystalline matter. Generalized displacement parameters are used to describe the weakening of Bragg intensities via the anharmonic (static or thermal) Debye–Waller factor (DWF) and its rea…
