Cement unlike anhydrite is a binder "resistant" to water and negative temperature. Cement screeds can be used in wet areas (without any restrictions) and outdoors. From the chemical point of view anhydrite is anhydrous calcium sulfate (CaSO 4 ) – a binder which is very similar to gypsum (formed by dihydrate calcium sulfate – 2H 2 OCaSO 4 ).

Analysis Of Anhydrite Gypsum Effects On Quality Of Cement. This article reports on the use of alternative calcium sulfate bearing materials, notably anhydrite, as cement retarders in cement pastes of CEM I and CEM II types. The aim of the study is to inquire the extent of natural gypsum replacement by natural anhydrite.
Details 
Cement milling and gypsum dehydration. Because the cement gets hot due to the heat generated by grinding, gypsum can be partly dehydrated, forming hemihydrate, or plaster of Paris - 2CaSO 4.H 2 O. On further heating, hemihydrate dehydrates further to a form of calcium sulfate known as soluble anhydrite (~CaSO 4).
Details 
Hemihydrate also was rehydrated to gypsum and in the process retarded the setting times and reduced the strength development of the cement. This has been further confirmed by examination of cements prepared with gypsum, hemihydrate, and anhydrite.
