Anhydrite

Anhydrite, also called calcium sulphate, is a common mineral from the mineral class of anhydrous sulphates with no foreign anions.

Milling anhydrites and adding a promoter creates anhydrite binders. These are air-hardening, non-hydraulic binders, which are comparable in their physical and chemical properties to gypsum. Calcium sulphate binders are used, for example, in residential construction to form calcium sulphate screeds or floating screeds.

Synthetic calcium sulphate binders are construction materials, which are produced with little energy and therefore save environmental resources.

Using these raw materials as a basis, Henge Baustoff developed the binder system "" and DuoFlow-Compound, which produce an optimal pourable floating screed for residential and commercial construction.
