ABSTRACT:
This invention provides a process of producing a building product, particularly a gypsum slab having preferably a density of below 800 kg/m.sup.3, with gypsum and mixing water. The quantity of mixing water required for rehydration and molding is at least substantially completely introduced into the gypsum by means of water saturated porous particles added in a distributed form. The process comprises the steps of intimately mixing water saturated particles with pulverous gypsum to form a fluid mixture; converting said fluid mixture at least almost completely without the application of pressure to the shape of a gypsum building product; permitting mixing water of the water saturated particles to be absorbed by the pulverous gypsum, and permitting the resulting mixture to set and harden.
