Abstract
Synthesis of Portland cement clinker from kiln feed raw materials containing zinc carbonate was studied. The kiln feed of the Portland cement was substituted by different contents of zinc oxide (0.0, 0.5, 1.0 and 1.5 wt. %). The ingredients of mixes were intimately homogenized, mixed, molded into a compact mass and fired at 1250, 1275, 1300 and 1325oC for two hours soaking time. The burnability of each sample was investigated by the determination of insoluble residue, free lime contents and phase composition of the fired products. The data show that the clinker formation was completed at 1300oC in the presence of 0.5-1.5 wt. % zinc oxide. Also, the prepared low energy cement has good hydraulic properties than those of the ordinary portland cement.
