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:
A pavement repair system utilizing solid phase auto regenerative cohesion and homogenization by liquid asphalt oligopolymerization technologies. The system is suitable for use in repairing asphalt pavement, including pavement exhibiting a high degree of deterioration (as manifested in the presence of potholes, cracks, ruts, or the like) as well as pavement that has been subject to previous repair and may comprise a substantial amount of dirt and other debris (e.g., chipped road paint or other damaged or disturbed surfacing materials). A system utilizing homogenization by liquid asphalt oligopolymerization is suitable for rejuvenating or repairing aged asphalt, thereby improving properties of the paving material.
Abstract:
A structural sandwich element, especially wall element, comprising at least one cellulose honeycomb core having a plurality of juxtaposed channels, the honeycomb core being accommodated between a first and a second cover layer. The first and/or the second cover layer is/are a concrete cover layer, especially from high-performance concrete, or a gypsum cover layer.
Abstract:
A building element (1) that is suitable for use as a structural element in wet areas or external docking. The building element (1) comprises a rigid substrate (2) having an upper face (3). Over the first face (3) lies a radiation curable resin (4) into which a layer of reinforcing material (5) is at least partially embedded. The reinforcing material (5) and resin (3) can be applied separately or together onto the first face (3) of the rigid substrate (2) or in some cases can be applied to both faces. An apparatus and method for producing the building sheet are also disclosed.
Abstract:
The present invention provides an inorganic board having excellent wind pressure resistance and long-term durability, and a production method of such an inorganic board.An inorganic board is obtained by laminating layers comprising a cement, a siliceous material and a woody reinforcement, and has a specific gravity ranging from 1.5 to 2.0; a dimensional change rate upon ten-day moisture desorption at 80° C. of no greater than 0.1%; a dimensional change rate upon seven-day moisture absorption of no greater than 0.1%; a seven-day dimensional change rate, in an environment having a carbon dioxide concentration of 5%, of no greater than 0.1%; and a flexural strength of not lower than 20 N/mm2. A method for producing an inorganic board includes a step of producing raw material slurry comprising a cement, a siliceous material and a woody reinforcement; a step of producing laminated mat by laminating sheets formed by dewatering the obtained raw material slurry; and a step of pressing the laminated mat at a pressure not lower than 50 kg/cm2, and curing the laminated mat at 170 to 200° C. in an autoclave.
Abstract:
A cementitious board and methods of making the same are disclosed by a cementitious board including a cementitious core, a plurality of warp yarns and weft yarns and a coating applied to produce a coating 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.

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:
The main object of the present invention is to provide an electromagnetic wave-shielding construction material which can cut-off electromagnetic waves at low costs in an efficient manner and a method for the production of the electromagnetic wave-shielding construction material. In order to achieve the above-mentioned object, the present invention provides an electromagnetic wave-shielding construction material comprising laminating an electromagnetic wave-shielding sheet, prepared by forming a conductive ink layer on one surface of a base material sheet by printing, on at least one plate surface of a panel section formed of a mixed material consisting of major panel components and a conductive material such that the conductive ink layer is in contact with the plate surface.
