Abstract
Three cement mixes containing different proportions of BaO.Al2O3 (BA), CaO.2Al2O3 (CA2) and MgO.Al2O3 (MA) phases were prepared and investigated for their mineralogical and chemical compositions. The physico- mechanical properties of the hydrated cement mixes were determined by means of setting time, refractoriness and compressive strength up to 1550 C. It was concluded that, as the amount of BA and CA2 increases at the expense of the MA content, the setting time (initial and final) and the mechanical properties are improved with decreasing refractoriness. So a cement mix containing intermediate proportions of BA, CA2 and MA show reasonable mechanical properties and relatively higher refractoriness. 14 refs.
