    Abstract: A lime pellet for use in asphalt applications is prepared to include lime fines and an asphalt-compatible binder. The pellet is characterized as having a rigid structure with a dimension greater than about 1.5 mm and being compatible with a hot mix asphalt so as to dissolve in liquid asphalt. The pellet is manufactured by mixing the lime fines with the asphalt-compatible binder and forming pellets therefrom. A benefit of the present method is the elimination of steps that cost time and money because limestone can be converted to quicklime, the quicklime is hydrated, and the pellet is formed in a continuous process or in a single system. The pellets are useful for conditioning an end product of hot mix asphalt during the manufacture of such an asphalt.

  • Patent number: 7662229
    Abstract: A cement setting accelerator comprising calcium hydroxide particles having an average particle diameter of 3 ?m or less, and a cement composition comprising 100 parts by weight of a cement and 0.05 to 10 parts by weight of the above setting accelerator. A wet ground product of calcium hydroxide or a fine precipitate formed by a reaction between a calcium salt and an alkali hydroxide can be used as the above calcium hydroxide particles. This setting accelerator shows a high setting accelerating effect and does not exert a bad influence upon the quality, especially durability of a hardened product of the cement composition.

  • Patent number: 7556685
    Abstract: The invention is a composition of an architectural papier-mâché, and articles made therewith. Articles formed from using the architectural papier-mâché have excellent weather resistance, and can be used outdoors, as well as indoors. The composition is comprised of cellulose insulation and a joint compound. Cellulose insulation is a paper-based material, like newsprint or phonebook paper that is shredded and chemically treated with boric acid, which imparts resistance to mold, mildew, fungus, insects, moisture and flammable combustion.

  • Publication number: 20090130452
    Abstract: Wallboards, as well as other building materials, are produced by methods which use significantly reduced embodied energy, generating far less greenhouse gases when compared with the energy used to fabricate gypsum wallboard. A novel cementitious core, consisting in one embodiment of post-industrial waste such as slag and combined with pH modifiers, provides a controlled exothermic reaction to create a gypsum-wallboard-like core which can be wrapped in a selected material such as recycled paper and manufactured on a conveyor system to appear, weigh and handle similar to gypsum wallboard, but without the large amounts of energy required to make gypsum wallboard. The manufacturing process results in lower greenhouse gas emissions than the processes used to make gypsum wallboard.

  • Patent number: 7527098
    Abstract: A wellbore may be cemented by preparing a cementitious composition comprising water, a metal oxide or hydroxide compound, a phosphate compound, a borate compound, and a sugar, followed by displacing the cementitious composition into the wellbore. The metal oxide or hydroxide compound reacts with the phosphate compound in the wellbore to set into a hard mass. The synergistic effect of the borate compound and the sugar may increase a thickening time of the cementitious composition to in a range of from about 2 hours to about 11 hours at ambient temperatures in the wellbore. As such, the thickening time is sufficient to allow the cementitious composition to be placed in its desired location in the wellbore before setting.

  • Patent number: 7427321
    Abstract: Disclosed are formulations adapted to form a foamed cementitious composition, the foamed cementitious composition itself, a method of forming a hydraulic binder foam, and a method of conveying and applying the resulting foam to a substrate. A pumpable cementitious slurry is formed, the slurry is mixed with a gas such as air, and is subjected to mechanically created turbulence to generate gas bubbles and create a foam, which preferably is stabilized by a foam stabilizing agent such as polyvinyl alcohol present in the slurry. The foam is then conveyed to a nozzle or other suitable dispense point from which it is applied, for example sprayed, preferably uniformly, onto a substrate to be coated. Prior to dispensing, a set accelerator is preferably injected, which causes the foam to gel, which in turn improves the hangability of the product on a substrate. The spray material adheres to the substrate and hardens to form an insulative coating on the substrate.
