ABSTRACT:
A moist mixture of plaster of Paris and fibres is produced due to the fact that before mixing with the fibres, a considerable quantity of water is supplied to the plaster of Paris, which leads to a moisture content of the plaster of Paris of up to 22% by weight (with respect to the dry substance). With this moisture content, the plaster of Paris is indeed no longer stable in storage in an unrestricted manner; however, it remains free from lumps for a certain processing time and can be mixed with the fibres in a high speed, continuous mixer. The moist mixture of plaster of Paris and fibres obtained in this way is intended as an initial product in the manufacture of fibre-reinforced moulded plaster bodies, in particular of fibre-reinforced plaster boards. It contains the water necessary fort setting in the most homogeneous distribution and in a precise dose (FIG. 1).
