Table II.

Phase Composition of the Reactants and Set Cements. The Measured Composition was Determined by Rietveld Refinement of the XRD patterns

			Initial powders			Set cements
	Nominal composition		Measured composition (XRD/Rietveld refinement)*			Measured composition (XRD/Rietveld refinement)*
