  • Patent number: 9926700
    Abstract: A rubber part for use as a structural component for incorporation into a brick or masonry wall structure in a reinforced concrete frame, to be located within the plane of the wall, has a length x and a stiffness along its length of Sx, a width y and a stiffness across its width of Sy, and a thickness z and a stiffness across its thickness of Sz, the stiffness of the part being anisotropic with Sy>Sx. The part is adapted such that, when in use, it is capable of controlling vibrations of the wall caused by seismic activity and also of having a damping effect thereby increasing the energy dissipation capacity of the structure. The rubber part is preferably in the form of a sheet and can be laminated on one or both major surfaces. The two major surfaces of the sheet may be contoured, for instance being corrugated across its width.

    Abstract: A method of manufacturing a prefabricated precast riser module, where the required forms that are used in casting the modules are reusable and need not to be transported to the construction site. Each precast riser assembly is finished having brick facings. Brick facings are applied to the vertical surfaces of the precast riser. They are: the commonly used stretcher course and row lock course. A Rebar reinforcing rod is imbedded in the concrete mixture, which will strengthen the assembly to prevent damage when being transported on site. This added strengthening would also allow for minor misalignments during the assembly phase. These novel concrete brick faced modules can be assembled by inexperienced craftsmen, and when completed, will give the appearance of a handcrafted riser that was constructed by professional masonry craftsmen using brick and sandstone.

    Abstract: A constructional panel 1 has a facing 3 which is brick or stone-like with mortar joints 4 therebetween and a backing 2 of cementitious material. The panel is cast using a mould mat 20 and a mask 30. The mat 20 is formed from a built panel and the mask 30 is formed from the 20. The mask 30 is used to provide realistic mortar joints between the facing elements 3.

  • Patent number: 6780369
    Abstract: A method of finishing concrete using a vibrating tool to consolidate a “dry shake” aggregate into the upper layer of the concrete. The use of the vibrating tool causes moisture within the concrete mass to migrate into the surface layer where the moisture may hydrate the aggregates in the dry shake mixture. The ability to cause upward migration of water in the concrete mass provides a larger window of finishability for the concrete. The vibrations also provide thorough consolidation of aggregates in the upper layer of the concrete mass helping to prevent delamination.

  • Publication number: 20040041295
    Abstract: An improved surface seeded exposed particulate concrete and method of making the improved surface seeded exposed particulate concrete is disclosed. Small particulate is sprayed over the upper surface of the concrete. The particulate may be sprayed using a material sprayer. The particulate may be uniformly sprayed to distances exceeding twenty feet. The particulate is mixed into a cement paste derived from the concrete mixture using floats. A surface retarder is then applied to cover the concrete surface. Subsequently, any surface film is washed from the surface of the concrete and the concrete is cured. The result is a surface seeded particulate with an exposed surface that is flat and is suitable for high traffic areas. The resultant surface may resemble stone, granite or marble.

  • Patent number: 6669876
    Abstract: A method of preparing a smooth watertight concrete in-ground pool surface that eliminates the use of a plaster outer surface layer that includes allowing the concrete pool body to cure for at least thirty days at which time a grinder is used to grind the surface to a smoothness and depth that is watertight and that exposes aggregates within the pool surface resulting in an aesthetically desirable permanently finished pool surface.

  • Patent number: 6635213
    Abstract: The subject of the invention is a method of manufacturing centrifuged, glass fiber-reinforced synthetic material pipes wherein liquid, curable resin, which contains a filler, together with glass fibers, additives for the curing process, possibly also with sand, is introduced into a rotating mould and the temperature of the mould is between 40° C. and 75° C. as the raw materials are introduced. The resin used in the layers in the outer region of the pipe has a gel time which is equal to or greater than the gel time of the resin used for the inner region of the pipe and the resin comprising a filler content of at least 40% is used. Furthermore, once the exothermal reaction has commenced, warm water is sprayed onto the mould in order to maintain the temperature of the mould at least at 60° C. until the pipe is removed.

  • Patent number: 6610224
    Abstract: A decorative aggregate-containing cementitious slurry having decorative aggregate and cementitious matrix composition forms a monolithic structure when effectively applied to a freshly poured cementitious base and simultaneously cured therewith. The slurry and the base are cured for a time sufficient for producing the monolithic structure with a decorative aggregate-containing cementitious surface. The slurry produces a decorative aggregate-containing cementitious layer having a cured thickness effective for permanently securing the decorative aggregate therein with a portion of the decorative aggregate exposed. Various decorative surfaces are produced without requiring expensive hand broadcasting of the decorative aggregate, and without expensive surface grinding. Dry components of the slurry are decorative aggregate and decorative cementitious matrix blend.

  • Patent number: 6554536
    Abstract: During manufacture of a sewer or tunnel lining section, sand-resin material is deposited over a mould, to define a central part of the section. Sand-resin material is removed using a wire arranged to lie a predetermined radial distance from the surface of the mould. The wire is passed around the surface of the sand-resin layer whilst maintaining the predetermined radial distance, the predetermined radial distance comprising, or being slightly greater than a preset minimum thickness. The use of a wire to remove excess sand-resin material has been found to be particularly effective, and surprisingly the excess material does not re-adhere to the underlying surface after the wire has passed. This is despite the required tackiness of the sand-resin mixture.

  • Patent number: 6503428
    Abstract: A process for manufacturing floor and wall coverings that produces a product a user may adhere to any wall or floor surface. The process begins by blending selected volumes of epoxy and aggregate into a vessel. A selected portion of the blended mixture is poured into a mold of selected geometry. A first piece of interlocking screening material is positioned over the first selected portion of the blended mixture. A second selected portion of the blended mixture is poured over the first interlocking screening material. A second piece of interlocking screening material is positioned over the second selected portion of the blended mixture. A selected portion of an adhering material is embedded into the top surface of the second interlocking screening material and the second selected portion of the blended molded mixture. The mold is cured and the product is released from the mold.
