The cement is based upon magnesia plus calcium chromate chromite, a complex mineral produced by the combination of lime with chrome oxide (Cr2O3) in an oxidising environment. Hydration is normally performed with a 30% aqueous solution of magnesium chloride hexahydrate (MgCl2.6H2O) solution at 8 per cent by weight of the cement. The products are complex. As well as hydrates they also consist
Expansion of Cement Containing Crystalline Magnesia
In the presence of slag, however, cement containing magnesia expands less under the autoclave conditions than under the normal conditions. This implies that one should be cautious when applying the autoclave expansion test to the cement containing slag or other mineral admixtures. The addition of fly ash and slag reduces the expansion of cements containing magnesia with their increasing
