摘要

A process for the fabrication of panel-shaped composite materials from lignocellulose-containing and/or cellulose-containing particles and/or fibres as well as hydraulic binder and additives is described, wherein a dry mixture of Portland cement, gypsum and reaction-accelerating mineral components is formed in a cold mixing step and this mixture is then blended with lignocellulose-containing and/or cellulose-containing particles which carry the water required for sending in the form of surface water, but essentially do not contain any cell water or any releaseable cell water. From this plan, a nonwoven is formed which is pressed to give the finished panel-shaped product within a relatively short time, with a rapid increase in the temperature of the nonwoven.
