  • Patent number: 7600309
    Abstract: A method of creating a smooth-to-the-touch Terrazzo pool finish is disclosed. A mixture of 1 part cement to 1-2 parts crushed marble aggregate, ¼ part pool sand, and sufficient potable water, is mixed until smooth and creamy in texture. The mixture is pumped to the gunite shell of a pool interior surface and hand trowelled onto the shell. In a still soft state, the trowelled surface is seeded with colored and/or high performance aggregate to create desired surface effects. The seeded elements are then trowelled into the upper layers of the surface until hard. After an initial set has taken, the surface is sprayed with a chemical retarder. Once fully set, following 10-20 hours of curing, the mixture surface is power-washed and diamond sanded until smooth-to-the-touch and acceptable in appearance in terms of exposing the previously seeded surface effects. The pool is then filled, chemically treated, and brushed until the surface is no longer dust producing.

  • Patent number: 7588797
    Abstract: A chemical composition and method for repairing a thermal barrier coating on a component designed for use in a hostile thermal environment, such as turbine, combustor and augmentor components of a gas turbine engine. The method repairs a thermal barrier coating on a component that has suffered localized damage to the thermal barrier coating. After cleaning the surface area of the component exposed by the localized spallation, a paste-like mixture of a ceramic composition comprising ceramic powders and nano-sized ceramic materials in a binder is applied to the surface area of the component, and is optionally smoothed using mechanical means. The composition is then allowed to dry and cure to form a dried coating having polymeric characteristics. Upon subsequent heating, the dried coating reacts to produce a glassy ceramic repair coating.

    Abstract: In a method of producing a flooring, a sub-floor is coated with a first layer of binder. A layer of aggregate material is spread over the binder which is then allowed to dry or set so that the particles bond therein. A second layer of binder is spread out over the first layer of binder and aggregate material bonded therein. A second layer of aggregate material is spread over the second layer of binder. Prior to drying or setting of the second layer of binder, the aggregate material of the second layer is mechanically processed to drive out air and in order to orient the particles of the aggregate material so that these turn their sharp edges and jagged tips away from the top side of the impending flooring. Finally, the flooring is allowed to dry or set, whereafter it is ground flat and even.

    Abstract: A method of making a grout composition which reduces the amount of bleed water from grout used in bonded post-tensioned concrete applications is provided. The method includes forming the grout composition by combining copolymers with other materials into a hydraulic cementitious composition. The copolymers are formed from structural components a) to c) and optionally d) which are mono-unsaturated compounds, with a generally linear macromolecular structure. By reducing the amount of bleed water in bonded post-tensioned concrete applications the grout composition provides protection from corrosion for the steel members, including stranded tendons and solid bars. The reduction in the amount of bleed water is achieved without significantly increasing the viscosity of the grout mixture thereby allowing good pumpability, placement, and maintenance of other properties such as resistance to volume change, long working time and acceptable strength development.

The matte being formed with first and second sets of cells extending from a side attached to the structure to an outer face thereof. The first set of cells are tapered having a narrow end adjacent the outer face and a wide end adjacent the wall structure. The second set of cells are tapered and having a narrow end adjacent the wall structure and a wide end adjacent the outer face. At least one first cell communicates with at least one adjacent second cell via a communication slot in the cell walls.

  • Patent number: 6458423
    Abstract: A sprayed-on phosphate cement coating formed from the combination and reaction of a phosphoric acid solution and a base metal solution. The acid solution and base solution may be intermixed prior to spraying, during spraying, or on a substrate. The curing reaction rate of the phosphate cement coating and its final physical properties may be controlled by adding various retardants, accelerants, reducers, wetting agents, superplasticizers, buffers, water reducers, adhesive agents, hardening agents, and/or sequestrants to the precursor solutions. The curing rate and properties of the cement coating may be further controlled by adjusting the temperature of the precursor solutions and/or the target substrate.

  • Patent number: 6444258
    Abstract: A method and apparatus of treating a pavement surface, including the steps of: applying a layer of bituminous sealant at a predetermined temperature and application rate on the pavement surface; applying a layer of bituminous emulsion at a predetermined temperature and application rate on the first of bituminous sealant, wherein a thermal reaction occurs between the bituminous sealant and the bituminous emulsion so as to accelerate a material break and cure time for said layers; and, providing a layer of aggregate particles at a predetermined application rate on the layers of bituminous sealant and bituminous emulsion during the thermal reaction. The steps of the method are performed successively along a particular direction of advance at a rate which permits them to be accomplished within a predetermined time period. Additional steps of compacting the layers and/or applying an asphalt layer thereon may also be performed.

  • Patent number: 6413336
    Abstract: A method and apparatus utilizing a plurality of complimentary flat planar surfaces having apertures forming a figure or object. The method of the present invention comprises the steps of positioning a planar body on a planar surface, applying drywall compound so as to fill the aperture or apertures, allowing the compound to dry partially, removing the planar body, replacing the planar body over the drywall mold, positioning a second planar body and removably attaching the second planar body, spreading drywall compound over the apertures in the second planar body, allowing the compond to dry and removing the first and second planar bodies. The apparatus of the present invention is the equipment required to carry out this method.

  • Patent number: 6406755
    Abstract: Improved sprayable gypsum-based fireproofing composition comprising a lightweight aggregate and a set retarding agent in an amount effective to delay the setting of said composition for at least 24 hours and preferably for at least 72-96 hours without causing the composition to swell or shrink or to cause a salt layer to form on the composition when it is spray-applied. The fireproofing composition can retain fluidity in conventional spray hoses overnight and yet is capable of being injected with a set accelerator, such as aluminum sulfate, on the next day or on a successive day when spray-applied onto a substrate.

  • Patent number: 6358753
    Abstract: The present invention relates to a method for binding antibody or antigen molecules to solid phase. The reactive compound comprising an antibody or antigen molecule and a solide phase are formed by coupling a specific antibody or antigen molecule to a solid phase using a two-step reaction. The coupling is covalent, between the active groups of the solid phase and the antibody, a fragment thereof or the antigen molecule, in the presence of an anionic surfactant, after adding an alkaline/solution to raise the pH to the basic region.

  • Patent number: 6314695
    Abstract: A stucco wall structure for a building. The wall substrate is arranged for receipt of subsequent layers of surface material. The margin or periphery of the wall to be treated has a screed attached thereto. A sprayed-on coating of urethane is applied onto the wall substrate between the screeds to insure continuous bonding and adherency to the substrate. A first layer of polymer-based base coat and mesh covering is applied to the sprayed-on coating of urethane to provide anchoring and adhesion of a subsequent layer of stucco. An outer layer of stucco applied over the first layer of polymer-based base coat as a final coat thereon.
