초록

Red gypsum waste comes from titanium dioxide production by sulphuric acid method. Anhydrite was prepared from thewaste. The effects of calcined temperature on the properties of anhydrite were studied. The normal consistency of anhydritedecreased with the increase of calcined temperature, while the compressive strength firstly increase and then decrease. Theeffect of high strength gypsum on the properties of anhydrite was also studied. The normal consistency of sample decreasedwith the increase of high strength gypsum content, while the setting time firstly decrease and then increase, strength anddensity increased.
