Abstract: A method of producing a laminate, wherein a wood body is provided, a curable composition in the liquid state is applied thereto, and the composition cures, wherein the composition contains at least one organic binder and at least 80% by weight of mineral fillers, based on the overall composition. The method enables permanent bonding of wood bodies and compositions that are based on organic binder and have a high content of mineral fillers. The laminates obtained from the method are comparatively lightweight, stable and durable, and are particularly suitable as sustainable components in building construction, especially as a roof element.

Abstract: A method for producing a laminate, wherein a wooden element is provided, the wooden element is coated on the top side with a an adhesive that is applied in liquid form and includes at least one polymer that is liquid at room temperature and contains silane groups, at least one liquid epoxy resin and at least one amine hardener, the applied adhesive is covered with a layer of a liquid cementitious composition while still wet, and the liquid cementitious composition and the adhesive each cure. The method enables the durable joining of wooden elements and cementitious elements in an easy-to-implement, wet-on-wet method. The laminates obtained from the method are comparatively light, stable and robust and are especially suitable as sustainable components in above-ground construction.
