Reinforced concrete structures and assemblies, building systems, and methods of fabrication.

A production plant for a ground covering structure (6) comprises a plant inlet zone and a plant outlet zone for a grid reinforcing member (10). The plant further comprises movement means (4) designed in operation to move the grid reinforcing member (10) along a predetermined path from the inlet zone to the outlet zone, supply means (11) for the supply of plastics material in the fluid state in the form of threads (7) to the reinforcing member (10) disposed along the predetermined path, and cooling means (2, 3) for cooling the plastics material in the form of threads (7) which are tangled on the grid reinforcing structure. The inlet zone and the outlet zone are disposed opposite one another along the predetermined path with respect to the supply means.

The present disclosure relates to intumescent fireproofing coatings and methods to apply these coatings. In particular, the disclosure relates to epoxy-based intumescent fireproofing coatings and methods of applying these coating having a mesh reinforcement.

A laminate of an at least partially reticulated thermoplastic film joined to an extensible carrier. The reticulated thermoplastic film includes a backing with openings and discrete elements protruding from the first major surface. There are two discrete elements aligned in a first direction abutting opposite ends of any given opening. In a second direction perpendicular to the first direction, there is one discrete element between the given opening and an adjacent opening aligned in the second direction. Each portion of the thermoplastic backing around the given opening is plastically deformed in its lengthwise direction. A method of making a laminate is also disclosed. The method includes stretching a thermoplastic backing having a plurality of discrete elements in the first direction and laminating the backing to an extensible carrier. Subsequently stretching the laminate in a second direction forms a tear in the thermoplastic backing between two adjacent of the discrete elements.

A novel nonwoven material for use as underlayment in landscaping is disclosed. The inventive method comprises creating a layered nonwoven material, identifying a landscaping location for receiving a portion of said layered nonwoven material; preparing a landscaping location; placing a portion of said layered nonwoven material on said landscaping location. The method may further comprise measuring a portion of said landscaping location; measuring a portion of said layered nonwoven material; comprise cutting one or more desired shapes from a portion of said layered nonwoven material; and securing a portion of said layered nonwoven material to said landscaping location by pushing one or more landscaping pins through said layered nonwoven material and into a portion of ground underneath said layered nonwoven material.

A pipe insulation product including a core of insulating material and a laminate surrounding the core and bonded to the core. The core may include an outer surface; an inner surface; and a wall extending between the outer and inner surfaces. The laminate may include a foil or metallized polymeric film sheet, a scrim, a porous media sheet, and a polymeric film sheet bonded together via an adhesive. The laminate may include a closure flap that is configured to adhesively seal opposite ends of the laminate together to form a cylindrical tube with the core enclosed therein. The closure flap may be configured to include a curl that provides a greater closure flap adhesive seal.

A microstructure comprises a plurality of interconnected units wherein the units are formed of graphene tubes. The graphene tubes may be formed by photo-initiating the polymerization of a monomer in a pattern of interconnected units to form a polymer microlattice, removing unpolymerized monomer, coating the polymer microlattice with a metal, removing the polymer microlattice to leave a metal microlattice, depositing graphitic carbon on the metal microlattice, converting the graphitic carbon to graphene, and removing the metal microlattice.

A composite foam article is disclosed herein. The composite foam article comprises a polyurethane foam core presenting a first surface and a second surface facing opposite the first surface. A first skin is disposed on the first surface and a second skin is disposed on the second surface. The polyurethane foam core has a density of 15-80 kg/m.sup.3. The first and second skins comprise a plurality of fibers and a polymeric binder. The composite foam article has a weight per unit area of 500-1000 g/m.sup.2 and a strength of greater than 17 N at a post-compression thickness of greater than 2 mm when tested in according with SAE J949 at 23 C.

In various embodiments, an improved flexible-composite material is described that comprises at least one scrim constructed from at least two unidirectional tape layers bonded together and at least one woven fabric, non-woven fabric, or membrane bonded to the scrim. In various embodiments, the unidirectional tape layers comprise a plurality of parallel fiber bundles comprising monofilaments within an adhesive resin. In various embodiments, the fiber bundles are separated by gaps that can be filled in by adhesive or non-adhesive resin.

A novel nonwoven material for use as a cover of bedding and furniture is disclosed. The inventive method comprises creating a layered nonwoven material, cutting one or more desired shapes from a portion of said layered nonwoven material; securely attaching a first portion of said one or more desired shapes to a second portion of said one or more desired shapes to create a cover containing an internal cavity; and placing a furniture item within said internal cavity of said cover. The furniture item is selected from a group comprising a pillow, a cushion, a mattress, and a duvet.
