    Abstract: A dry papercrete mix containing a pulp of fiber material such as newsprint and sharp sand, Portland cement and adding additional sand and/or pumice. The resulting dry, granular mix can then be handled stored and used in the manner which is conventional for concrete. The dry papercrete mix can be fortified with a fiber form of basalt which can be added to or substituted for all or a portion of the cellulose fiber content of the dry papercrete mix to provide a stronger structure when hydrated and cast into a desired shape with only a small increase in weight. Basalt reinforcing bars and meshes may be included in shapes cast from the hydrated mix in combination with or substitution for steel reinforcing structures. Including basalt in the mix and in reinforcing systems allows the design of joints between structural modules to provide exceptional strength in a unitary structure so formed.

    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.

  • Patent number: 8038790
    Abstract: Structural cement panel for resisting transverse and shear loads equal to transverse and shear loads provided by plywood and oriented strain board, when fastened to framing for use in shear walls, flooring and roofing systems. The panels provide reduced thermal transmission compared to other structural cement panels. The panels employ one or more layers of a continuous phase resulting from curing an aqueous mixture of calcium sulfate alpha hemihydrate, hydraulic cement, coated expanded perlite particles filler, optional additional fillers, active pozzolan and lime. The coated perlite has a particle size of 1-500 microns, a median diameter of 20-150 microns, and an effective particle density (specific gravity) of less than 0.50 g/cc. The panels are reinforced with fibers, for example alkali-resistant glass fibers. The preferred panel contains no intentionally added entrained air. A method of improving fire resistance in a building is also disclosed.

  • Patent number: 7972434
    Abstract: Ceramic precursor compositions and chemically bonded ceramic (CBC) materials, especially Ca-based, and a composite biomaterial suitable for orthopaedic applications. The CBC-system includes a binding phase (chemical cement) and additional phases with specified chemistry imparting to the biomaterial the ability of initial strength followed by interaction with the body tissue including body liquid, to form a resorbable or partly resorbable biomaterial. The ceramic precursor composition includes at least one silicate with Ca as the main cation with a resorption rate less or equal to that of the bone in-growth rate. The silicate will form the binding phase of the cured material. Implants and surface coated devices are also disclosed. The cured material exhibits a compressive strength exceeding 100 MPa.

  • Patent number: 7931952
    Abstract: A water-retainable molding is formed by mixing and hardening cement, fiber bundles and fiber masses, and includes first pores inside the fiber bundles, second pores between fiber bundles and a cement gel, third pores inside the fiber masses, fourth pores between the adjacent fiber masses, and fifth pores due to discharge of water content and air inside a platelike block. The first, second and fifth pores are employed as a capillary portion, the third pores are employed as a water-retaining portion, and the fourth pores are employed as a water communicating opening portion. When water is supplied to the surface, the water is absorbed from the fourth pores as well as the first, second and fifth pores, and is retained in the third pores. Furthermore, when the temperature rises, the water content is supplied from the third pores to the surface through the first, second and fifth pores so as to be evaporated and to control the temperature of the molding.

  • Publication number: 20100224101
    Abstract: The method for recycling construction and demolition fines involves using mixed fines from construction and demolition debris that would otherwise be disposed of at landfills as an ingredient in cement or concrete. The mixed fines contain a plurality of materials selected from the group consisting of asphalt, plastics, ceramics, fiberglass and batt insulation, soil, dust, drywall, wood, plaster, paper, cardboard, dirt. The fines may also contain particles of recyclable materials, such as concrete, bricks, mortar, metals, glass, and the like. The fines may range in size from microns up to 6 inches in at least one direction. The recycler may incorporate the fines into a concrete mix for bulk sale to commercial enterprises, or may himself form precast, lightweight concrete products, such as decorative columns, pedestals and table bases, trim moldings and cornices, door surrounds, etc.
