▎ 摘　　要

NOVELTY - The building product has graphene and/or graphene oxide. The building product is a building board. The building board comprises graphene and/or graphene oxide in form of layer. The layer is present on surface of building board. The building board comprises multiple identical and/or different material layers and layer is placed between two of these layers. The layer is applied over full area or a partial area on this surface or between these two material layers. The layer comprises individual strips. The strips extend in longitudinal and/or transverse direction of building board. USE - Building products such as building boards. ADVANTAGE - The mechanical properties of the building boards are improved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for producing building boards.
