DURABILITY OF PHOSPHOGYPSUM BASED WATER-RESISTANT ANHYDRITE BINDER

Data on the durability of a phosphogypsum based water-resistant anhydrite binder as affected by weathering under conditions of alternate wetting and drying as well as heating and cooling cycles at temperatures from 27 to 60 degrees C are presented. The results show that strength of the binder is reduced and loss in its weight increases with increase in exposure temperature. There is a drastic reducation in strength beyond 45 degrees C. As compared to the plain hemihydrate plaster, the binder, however, shows much lower fall in strength and loss in weight.(A)
