Our phosphoric acid manufacturing
plant in Engis, Belgium is the only phosphoric acid plant
in the world producing calcium sulphate that is pure
enough for use in the plaster industry (floor gypsum,
manufacture of boards, blocks and tiles,self-levelling
coating, etc.). Its whiteness particularly fits for floor
gypsum.
In the cement industry, calcium sulphate is used as
a 'retarder'.
