For the production of building products with a higher final strength compared to the use of conventional beta-hemihydrates:
Calcium sulphate-α-β-hemihydrate Finely ground :
For use in industrial applications for the production of building products having a
higher final strength compared to conventional β-hemihydrates:
- As a sulphate carrier in building chemical products, e.g.levellin compounds, floor compounds, screeds
- As a gypsum binder according to DIN EN 13279-1 for further processing, e.g. for premixed gypsum building plasters for plastering and gypsum-based compounds for filling and finishing work in solid and drywall constructions.
- As model and/or mould material for coarse and/or fine ceramic applications in the production of e.g. roof tiles, sanitary ceramics, earthenware, stoneware.
- As an input material of inorganic origin produced in Germany without additives, e.g. flow aids
