Özet

In this study, samples of Calcium Aluminate (CA) cements produced from reactive alumina and calcite were compared with those samples produced from Bayer - Al(OH)3 and calcite. The raw material mixtures were formed under light pressure into cylinders and sintered at 1350, 1400, 1450 and 1500°C. The fired samples were ground to 3300-4400 cm2 /g Blaine in a laboratory ceramic mill. The physical and mechanical properties of the cement samples were determined. The results of this study suggest that the production of CA - cements containing 71 % Al2O3 was possible using Bayer- Al(OH)3 and calcite as raw materials.
