Abstract

The invention relates to a method for producing a hydraulically-bonded multilayer panel with at least one face layer and at least one core layer, wherein the method comprises the following steps

a. introducing a flowable face mixture into a mold. The face mixture contains at least the following componentsi. face paste containing at least1. hydraulic binder and2. water; andii. aggregate. The aggregate has a mean diameter d50 determined according to ISO 13320:2009 and/or according to EN 12620 of greater than 100.0 μm;whereby a face mixture layer is formed;b. introducing a dry to earth-moist core mixture into the mold, wherein the core mixture contains at least the following componentsi. core paste containing at least1. hydraulic binder,2. fines, wherein the fines have a mean diameter d50 determined according to ISO 13320:2009 of up to 100.0 μm, and3. water; andii. aggregate, wherein the aggregate has a mean diameter d50 determined according to ISO 13320:2009 and/or according to EN 12620 of greater than 100.0 μm;whereby a core mixture layer is formed, andc. pressing the face mixture layer with the core mixture layer into the mold to form a hydraulically-bonded, directly strippable multilayer panel with at least one face layer and at least one core layer, wherein water contained in the face mixture layer is partially or completely pressed into the core mixture layer
