Methods of preparation of phosphogypse for the Manufacture of binder

Abstract

From the point of view of building materials manufacturers, the method of deep neutralization of phosphogypsum in lime suspension and the possibility of one-stage and stable conversion of acid fluoride and phosphate compounds into low-soluble compounds such as hydrosilolapatite and calcium fluoride are the most acceptable. The resulting gypsum is used for the production of partitions, decorative products and drywall. Priority methods of preparation of phosphogypsum for the production of air binders are considered.
