The invention comprises a relatively lightweight cementitious-based material panel. The cementitious-based material panel comprises a foam insulating panel having a first surface and a second surface; a first structural layer of cementitious-based material formed on the first surface of the foam insulating panel and affixed thereto; and a second non-structural layer of cementitious-based material formed on the second surface of the foam insulating panel and affixed thereto. The second non-structural layer of cementitious-based material is substantially thinner than the first structural layer of concrete. The second non-structural layer of cementitious-based material is preferably formed from polymer modified concrete, plaster or mortar. A method of making the cementitious-based material panel is also disclosed.

Gypsum panels, methods for their manufacture, and systems and methods for monitoring environmental conditions with such panels are provided herein. The panels include a gypsum core having a first surface and an opposed second surface, a first facer material associated with the first surface of the gypsum core, and an environmental sensor assembly associated with the gypsum panel and configured to detect an environmental condition of the gypsum panel and wirelessly communicate data on the environmental condition to a reader.

Disclosed is a board structure for manufacturing concrete products, wherein a board used to manufacture a concrete product, for example, concrete blocks, paving stones, etc. is formed of an upper layer and a lower layer, and a side support frame connecting the upper layer and the lower layer, so it does not need to manufacture molds for each size, and a portion that receives external weight during the manufacturing of concrete products can be reinforced, thus obtaining substantial strength and lightness, and the manufacturing does not cost a lot while reducing noises during the manufacturing of concrete products.

A panel, such as a floor panel, including a core, an optional upper arrangement and an optional lower arrangement. One or more of the core, the upper arrangement (5) and the lower arrangement includes a mineral-based layer, preferably including magnesium oxide. One or more of the mineral-based layers includes reinforcement fibres embedded in a mineral-based matrix, preferably including magnesium oxide. The fibres are configured to increase the tensile strength of the mineral-based layer.

A heat insulation sheet and a sheet material using the heat insulation sheet. The heat insulation sheet is provided with a fixing layer that is arranged between a base material and a carbon sheet. The fixing layer is made of a pressure-sensitive adhesive. The base material has flexibility. The carbon sheet is made by rolling expanded graphite and has a thickness from twenty-five micrometers to one hundred micrometers. In the sheet material, activated carbon is arranged opposite to the fixing layer side of the heat insulation sheet, and a surface material is arranged on a surface of the activated carbon. The fixing layer can be constituted in such a manner that a hot-melt adhesive is arranged in a reticulate manner.
