Abstract

The amount of chemical gypsum contains the stoichiometrically necessary quantity of water for the final setting, or a multiple thereof; other aggregates are opt. present as well. The chamical gypsum may come from phosphoric acid mfr. The treated plaster is opt. reactivatable anhydrite II, e.g. as Keene's cement. Moulding is opt. performed by compression at 150-450 kg/cm2. Cheap high strength moulding results.
