Also, if it does not make contact with water during cooling, its mortar mixture shows a very short setting time of 8 min and high compressive The Calcium Aluminate range is a family of sophisticated hydraulic refractory binders designed for use in high technology monolithic refractories. Ranging from 45% alumina to 80% alumina and fineness upto 4500 blaine, these products ensure rapid hardening, superior corrosion resistance and excellent thermo-mechanical performance of the The tricalcium aluminate powder was soaked in SBF solution (solid/liquid ratio of 0.5 mg/ml) into a bath at 37 °C, for 7 days, without refreshing the SBF. The powder was then filtrated, washed with ethanol and dried at 40 °C for 24 h. After drying, the powder were analysed by XRD and SEM (EDX). Calcium aluminate cement is a kind of cement, in which mineral compositions are CaO·Al2O3 and CaO·2Al2O3. As unshaped refractory material, the properties is superior, which can withstand high temperature over 1650℃ and have high strength in the early period. EL-70 is calcium aluminate cement obtained from fusion of high purity bauxite and calcium carbonate in electric arc furnaces. It is ball milled with alumina addition which makes EL-70 an ideal product for special refractory applications.
