Utilization of phosphogypsum in portland cement industry
AbstractDisadvantages associated with the presence of impurities in phosphogypsum can be overcome when, instead of adding it directly to portland cement as a set-retarding additive, it is added to the raw mix before clinkering. Due to the mineralizing action of phosphogypsum, the clinker can be made at a substantially reduced temperature. Cements made by grinding a clinker containing 2 percent SO3 derived from phosphogypsum did not need any further retardation and possessed high early strength characteristics.
