  • Patent number: 8399089
    Abstract: A nanomaterial based admixture improves the fire retardancy of foam-based GFRC material to a minimum of 3 hours, creating Nano GFRC. A dispersion of nanoclay in water is prepared by heating water to 80-90 ° C., adding the desired amount of nanoclay and stirring with a magnetic stirrer for 30-45 minutes, producing a stable and uniform dispersion. Concrete is made by mixing sand, acryl, water, nanoclay solution, and cement in a bucket, adding enough water reducer to thin the mixture enough to stir, adding fibers, and mixing the composite using a rotor for about 10 minutes. Polystyrene foam is sandwiched with the prepared mixture on all sides to make the concrete. This resulting concrete is lightweight and strong, reduces CO and CO2 emissions by a factor of three compared to standard GFRC, and shows dramatic improvement in fire retardant properties.

    Abstract: A wall is formed by adding a predetermined amount of binding agent and water to volcanic ash sediment, which is comprised of mineral silicate including at least silicic acid and aluminum oxide, kneading them, and applying to an arbitrary plane. Through a natural reaction of positive ions included within mineral silicate and moisture included within the atmospheric air, thereby exchanging ions, minus ions are generated on an application plane. The amount of minus ions generated is, in a unit volume, between three and six times as many as that of the minus ions generally included in the atmospheric air. The combination of this application plane and humidity control apparatus is used as a minus ion generation system through adjustment of amount of moisture included within the atmospheric air so as to control the ion exchanging rate.

  • Patent number: 6913645
    Abstract: A combination of compositions, products and methods of producing a new type of cement. The cementitious material is created by adding sodium carbonate (also known as soda ash, trona, natron, sodium carbonate decahydrate, sodium carbonate anhydrous, etc.) and one or more rocks or minerals selected from the following—granite, basalt, sandstone or schist. A new method and product are claimed by combining sodium carbonate and one or more rocks or minerals selected from the following—granite, basalt, sandstone or schist and water. The combination of sodium carbonate and one or more rocks or minerals selected from the granite, basalt, sandstone or schist group can be either layered or mixed in a dry or wet state. An exothermic reaction starts after the addition of water to the cementitious material.

  • Publication number: 20040118561
    Abstract: Cement comprising barite, a process for preparing such cement, and methods of cementing in a subterranean formation or well bore using such cement are provided. The cement is prepared by introducing coarse barite to the cement, the course barite comprising particles having a particle size primarily greater than about 125 microns. Preferably, 90 percent of the barite particles is greater than about 125 microns in size. The presence of the coarse barite in the cement causes the cement to have a relatively low viscosity. Introducing the barite to the cement also increases the density of the cement, thus rendering the cement capable of controlling high hydrostatic pressures in a well bore.

  • Publication number: 20030118767
    Abstract: An adhesive composition and improved rolled product employing an adhesive composition is disclosed. Synthetic clays in combination with water soluble and dispersible thickeners may be useful for controlling the viscosity of adhesive formulations used in rolled paper product manufacture. The compositions may provide thixotropic properties, which are capable of shearing to a thin and sprayable viscosity, and then rapid thickening upon a surface of a rolled product. The rolled products to which the compositions may be employed may include tissues, towels, and the like. The compositions may be employed as tail sealing compositions adapted for securing the tail of a rolled web of product upon the roll, to avoid unraveling or undesirable unwinding of the roll before the product is used for its intended purpose upon manufacture.

  • Publication number: 20020117090
    Abstract: One kind of super high strength concrete, by adding some zeolites to cement, in order to attain the objective of shortening the time of hydration of cement, so that the concrete shows higher initial compressive strength. Zeolites and cement can undergo the Pozzolanic reaction which results in less void content and higher final compressive strength, so we can get super high strength concrete.

  • Patent number: 6251179
    Abstract: A thermally conductive cement-sand grout for use with a geothermal heat pump system. The cement sand grout contains cement, silica sand, a superplasticizer, water and optionally bentonite. The present invention also includes a method of filling boreholes used for geothermal heat pump systems with the thermally conductive cement-sand grout. The cement-sand grout has improved thermal conductivity over neat cement and bentonite grouts, which allows shallower bore holes to be used to provide an equivalent heat transfer capacity. In addition, the cement-sand grouts of the present invention also provide improved bond strengths and decreased permeabilities. The cement-sand grouts can also contain blast furnace slag, fly ash, a thermoplastic air entraining agent, latex, a shrinkage reducing admixture, calcium oxide and combinations thereof.

  • Patent number: 6061956
    Abstract: A method for supplying dry sand for spreading on road surfaces in freezing temperatures in a condition in which the sand remains fluid in freezing temperatures without the addition of salt includes the steps of drying the sand by providing a naturally occurring bed of the sand having an upper surface of the bed exposed to sunlight; planting on the upper surface a covering crop of a type such as alfalfa having deep roots which extend through the whole bed up to thirty feet deep in search of a water table below the bed and growing the crop for a period of time sufficient to allow the roots to penetrate the bed and to extract moisture from the bed to dry the sand in the bed. The dry sand is extracted from the bed and stored temporarily in a closed storage which prevents the re-introduction of moisture for subsequent use on road surfaces without the necessity of salt to keep the sand fluid for spreading.
