Phospo Gypsum

I want to use phospo gypsum for preparation of slag cement. I want to know the methods to reduce the acidity of phospo gypsum  to make it suitable for slag cement manufacturing without which the self life of cement reduces and cement detoriates very fast.

re Phospo Gypsum

Dear chari !

I told about it in this topic http://www.cemnet.com/Forum/thread/108993?page=1

We use for deep neutralization  of phosphogypsum a  compacting with high pressure on roller presses.  Before pressing we introduse  in phosphogypsum CaO, Al(OH)3, Fe(OH)3 or some of indastrial wastes.
