INPACT OF MECHANICAL ACTIVATION OF PHOSPHOGYPSUM RAW MIX ONTO HIDRATION AND CONCRETING OF ANHYDRATE BINDER

The paper presents the results of the research carried out on the production of anhydrite binder made of phosphogypsum stored for a long time in a heap. There was determined the influence of the phosphogypsum mixture mechanical activation time on the hydration of the anhydrite binder produced from such mixture. It was found out that due to mechanical activation of the raw mixture the strength of the anhydrite binder increased by 30-40% whilst the water resistance coefficient raised till 0.8-0.9.
