Abstract
The paper studies the possibility of using calcium-ferritic slag in the cement production. The chemical analysis shws the instability of the calcium-ferritic slag composition. Experimental and test raw mixtures are fired at similar temperatures without deterioration of the clinker formation process of raw mixtures containing calcium-ferritic slag. The quality evaluation of clinkers is performed for cements obtained by grinding with the addition of 4 % calcium sulfate up to a specific surface of 300 cm2/g. This paper shows the possibility of using the calcium-ferritic slag obtained during the complex processing of pyrite as a correcting component of the raw mixture at its consumption 1.3–1.5 times higher than pyrite cinders.
