VALORISATION OF PHOSPHATE CHEMICAL GYPSUM BY USING IT AS MINERALIZTER IN CEMENT CLINKER

摘要：

This paper studies the effect of phosphogypsum on the temperature clinkerization and the cement properties. The results of this study show that phosphogypsum, under the optimal conditions, influences positively the technological parameters of clinker. It is thus advised to use it as mineralizer in the raw mixtures, since it enables to reduce the burning temperature by almost 250℃.
