An X-ray study of pulverised fuel ash
Autor: J. W. Jeffery, H. S. Simons
Publikováno v: Journal of Applied Chemistry. 10:328-336
Pulverised fuel ash has been subjected to X-ray examination and chemical analysis and the main mineralogical and physical characteristics have been determined. It is shown that the ash is a very complex material in which the overall chemical composit

Structurally related dicalcium silicate phases
Autor: P. Barnes, J. W. Jeffery, C. H. Fentiman
Publikováno v: Acta Crystallographica Section A. 36:353-356
From careful measurement and indexing of the powder diffraction patterns obtained for pure dicalcium silicate, unit-cell parameter vs temperature plots have been obtained covering the β and α' dicalcium silicate phases. It is found that these phase

X-Ray Diffraction by a Crystal Possessing Periodicities within the Unit Cell
Autor: J W Jeffery
Publikováno v: Proceedings of the Physical Society. Section A. 64:1003-1006
The Fourier transform of a crystal is used to explain the appearance of the x-ray reflections from the true crystal lattice of tricalcium silicate as satellites of the strong reflections corresponding to a pseudo-lattice. Similar but more general dif

A new hypothesis of sulphate expansion
Autor: S. Chatterji, J. W. Jeffery
Publikováno v: Magazine of Concrete Research. 15:83-86
Summary On the basis of published data and their own observations, the authors suggest that sulphate expansion is caused by the solid state conversion of C4AH13 to calcium aluminate monosulphate and that this expansion mayor may not be accommodated d
