PERFORMANCE CRITERIA FOR THE USE OF FGD GYPSUM
FGD gypsum is evaluated as a possible partial or total substitute of natural gypsum for the control of cement setting. Extended laboratory and industrial scale trials in cement and concrete mixes were carried out. FGD gypsum after been dried presents an excellent performance compared with natural gypsum.Analysis of anhydrite gypsum effects on quality of cement,on cement production is likely to be seen. Application of phosphogypsum can be given as an example for this case. Phosphogypsum is a raw material which is produced from orthophosphote as a byproduct and contains CaSO 4 as a dust form. Remainder of phosphor and fluoride can be completely separated by washing and chemical ways. However, the gypsum in the phosphogypsum converts to anhydriteGypsum - Wikipedia,Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO 4 ·2H 2 O.
