Mineralizing action of phosphogypsum in burning of cement clinker

Abstract

Phosphogypsum accumulated in the dumps of JSC «Gomel Chemical Plant» in amount as much as 20 million tons could be one of the promising raw materials for cement production. The use of phosphogypsum in the cement industry as a mineral-izer for clinker burning process has been studied. It has been shown that the introduction of phosphogypsum in the feed mixture has a positive effect on the binding of calcium oxide during burning. The phase composition of clinkers and main properties of portland cement produced with the use of phosphogypsum, have been investigated.
