ANHYDRITE BINDERS FROM PHOSPHOGYPSUM AND DOLOMITE
The paper shows the possibilities of processing phosphogypsum of a mineral fertilizer plant, where more than 1 million tons of phosphogypsum are produced annually. This phosphogypsum is not currently in use. The authors proposed the composition and technology of processing phosphogypsum into anhydrite binder using a dolomite hardening activator. The strength of the binder reaches 29.3 MPa.
