A jointless surface covering can be applied to building parts by a method and a device (2). A flow of a surface covering material (37, 92) and of an adhesive (94, 95) is sprayed onto an underlying plane which is situated on the building part. The surface covering material forms an insulation for the building part. Granules (92) are used for the surface covering material. The granules are misted with adhesive (94) and, carried by air, they reach an area to be covered, wherein the granules immediately adhere as a result of the adhesive, which undergoes a chain reaction. By virtue of the device (2), granules are supplied from a granules reservoir (8) and adhesive is supplied from an adhesive reservoir (46) and brought together in an air space via a nozzle assembly (60) in order to form the surface covering. A combing device (16) serves for separating granular particles (92), which pass into a flow channel (28) via a chute (24). In the flow channel, the granular particles are taken up by an air flow (36) from a fan (30) and fed to the air space.

A wall panel includes a frame provided with vertical battens. The frame defines a plurality of holes. A connecting plate is formed by a mixture of a curable material in which organic plant-derived elements are embedded. The wall panel includes a thermal insulation layer. A facing layer is separated from the connecting plate by the frame and thermal insulation layer. A plurality of connectors are fixed to the frame. Each connector has a salient area spaced apart from the frame and embedded in the connecting plate. The connecting plate partially overlaps the vertical battens in the thickness direction, the connecting plate forming wood-concrete studs that partially fill the plurality of holes.

Mortar composition and its use in construction, mortar composition for construction having biomass ashes from agricultural and forestry residues, agro-industrial residues selected from almond shell or cork, resins, a binder selected from calcium oxide or calcium carbonate and water. Such a composition presents environmental advantages by employing residues of different origins in complete substitution of cement and sand, typically used in mortars. The mortar composition of the present invention can be used both in traditional construction and with 3D printers, particularly for masonry and coating.

The product is produced from a settable aqueous calcium sulphate dispersion which has a water to solids ratio of less than 0.4 to 1, and has distributed therethrough lightweight hollow bodies having water-impervious surfaces (such as expanded polystyrene beads). The dispersion contains a hydratable cement (such as calcium sulpho aluminate) which is capable of hydration in the presence of the calcium sulphate dispersion. The hydratable cement is such that it reacts with excess water in the dispersion thereby enhancing the water resistance of the resulting product.

Disclosed is a construction material composition including a matrix predominantly containing an aluminum silicate compound, such as a metakaolin, and an alkaline activation solution. The composition is contains less than 10 wt. % cement or clinker and in that the metakaolin is a metakaolin obtained via flash calcination. The reaction between the components is carried out at a temperature less than 30 C. The method for manufacturing the construction material includes mixing the composition with various elements such as granulates, plant fibers, unfired clay, and expanding agents. It is particularly of use in producing floor, wall, or roof coating elements, prefabricated construction elements, or insulation, adhesive, or inorganic sealant modules.

A method for producing a thermally insulating mortar includes introducing water, cement and a liquid surfactant containing a foam concentrate that forms a foam in a predetermined mixing ratio into a mixing device provided with a mixing impeller, and rotating the mixing impeller at a very high speed, wherein a homogeneous mixing between the water, the cement and the formed foam occurs.
