The core layer includes a layer of a cementitious mineral material which includes a cement and a dispersant. The invention further relates to a decorative covering, in particular a decorative floor covering, decorative ceiling covering, or decorative wall covering, including a plurality of interconnected decorative panels.
Abstract:
Disclosed herein are low density fiber cement articles, such as fiber cement building panels and sheets, comprised of multiple overlaying fiber cement substrate layers having small and uniform entrained air pockets and low density fillers distributed throughout. The combination of entrained air pockets and low density fillers provide a low density fiber cement matrix with physical and mechanical properties similar to comparable low density fiber cement matrix without entrained air pockets.
Abstract:
A composite structure having a solid-phase concrete base-substrate component; a fibrous component that is a plurality of polypropylene fibers, at least a portion of which are embedded into and thereby mechanically attached to the solid-phase concrete base-substrate component, wherein at least a portion of the fibers extend from within the concrete base-substrate component and out of the concrete base-substrate component through an exterior surface of the concrete base-substrate component; and a polyvinylchloride-adhesive layer component having a first and second surface, wherein the polyvinylchloride-adhesive layer component first surface is in contact with and adhesively attached to the fibrous component, and wherein the polyvinylchloride-adhesive layer second surface is in contact with and adhesively attached to a first surface of a polyvinylchloride or polyvinylchloride-containing-alloy exterior sheet.
Abstract:
The core of the invention is a method for producing a tubbing of concrete for jacketing a tunnel, in particular a traffic tunnel, wherein the tubbing has a convexly curved outer surface and a concavely curved inner surface opposite the outer surface, comprising the steps a) placing a membrane comprising a hot-melt adhesive layer and a thermoplastic sealing layer on the outer surface and, furthermore, on all sides of the outer side surfaces of the tubbing, which sides face the outer surface, wherein the hot-melt adhesive layer faces the tubbing; b) supplying heat under the partial melting of the hot-melt adhesive layer; and c) cooling the hot-melt adhesive layer with formation of an adhesive composite between membrane and the tubbing.
Abstract:
Panels for use in building construction (partitions, walls, ceilings, floors or doors) which exhibit improved acoustical sound proofing in multiple specific frequency ranges and also present improved structural integrity, are provided. The improved performance is achieved through the use of one or more layers of glue such that at least one layer of glue includes a viscoelastic material in a first pattern and a structural adhesive in a second, non-overlapping pattern. The viscoelastic material may have a varied shear moduli and functions as a glue and energy dissipating layer. In some embodiments, one or more constraining layers separating one layer of glue may be included. The constraining layer may be formed of a material such as gypsum, cement, metal, cellulose, wood, or petroleum-based products such as vinyl, plastic, or rubber. In some embodiments, standard wallboard, typically gypsum, comprises the external surfaces of the laminated panel.
Abstract:
The present invention is a method of making a backerboard having a fiberglass mesh on one side, and an impervious reinforcement membrane on the other side. The backerboard incorporates a low density, high compressive strength concrete core having an upper principal surface and a lower principal surface. The upper principal surface of the core is covered by a fiberglass mesh reinforcement layer, itself covered and bonded to the core by a thin layer of Portland cement. The lower principal surface of the backerboard is covered with a high tensile strength, impervious reinforcement membrane.
Abstract:
Fabric and reinforcements are provided by this invention which, in a first embodiment, include a plurality of warp yarns having a first twist (turns/inch) and a plurality of weft yarns having a second twist which is greater than the first twist. A coating is applied over a substantial portion of the warp and weft yarns after they are assembled or laid together, so as to produce a weight distribution ratio of less than about 2.0:1, based upon the weight of the resinous coating of the weft yarns over the weight of the resinous coating on the warp yarns. This can be achieved, in substantial part, due to the difference in the twist ratios of the warp and weft yarns, which difference permits a more uniform coating to be applied. Further embodiments of this invention include a cementitious board and methods of making a coated fabric and cementitious board.
Abstract:
A process for producing a perforated board comprising a cementitious layer and first and second facers is provided, the process comprising: (a) providing a substrate comprising a first facer; (b) applying a slurry comprising a cementitious material on the substrate; (c) providing a second facer above the slurry; and (d) forming a plurality of perforations which extends at least partially into at least one of the first and second facers.
Abstract:
The present invention relates to a stone like laminate that comprises a support layer made from a cementious matrix board and a surface layer. The surface layer comprises a high percentage of particles from an inorganic material such as stone particles and a low percentage of a resin, such as a polyester resin. The stone like laminate of the present invention can be produced at low cost and provides a aesthetic laminate that is highly resistant to heat, water and pressure.
Abstract:
The invention relates to a marine vessel, such as ships, floating platform etc, where the whole or part(s) comprises a layered structure and a layered structure for use in vessels, including two substantially parallel metal sheets with a concrete layer in between, where the concrete has density significantly less than that of normal concrete, preferably less than about 1200 kg/m3, where the layered structure is dimensioned as if the concrete layer in the structure carries essentially no tension but is capable of carrying compressive forces and support the metal sheets. The invention also regards a method for improving carrying capacity at existing structures, and an improved corrugated structure. The invention also includes a layered structure module, elements for building a module, and methods for producing a layered structure according to the invention.
