This invention relates to improved aluminous cement/gypsum compositions that contain polymer latex emulsions or compounds to produce self-curing, crack-free, fast-setting, high early strength, high bonding, water resistant, durable, cementitious mixtures for finishing, coating, plastering, stucco, rigid insulation protection, topping, resurfacing, patching, motaring, tile grouting, concrete, and the like. In addition, this invention discloses a method for improving the properties and performance of aluminous cement/gypsum compositions by adding certain types, amounts and/or combinations of polymer latex emulsions or compounds with or without the addition of wet expansion and drying shrinkage inhibitors.

Compositions and methods for the deposition of ettringite (3CaOA12O33Ca(SO4)30-32H2O) onto the surfaces of fibers, aggregates, and other fillers The ettringite is produced in situ within an aqueous suspension while in proximity to the fibers, aggregates, or other fillers to form a mineralized composite material comprising ettringite coated fibers, aggregates or other fillers Ettringite treated fibers, aggregates, or other fillers are formed by adding chemical reactants such as calcium oxide and aluminum sulfate, which react together in the presence of water to form ettringite, which then precipitates onto the surface of the fibers or other substrates being treated The ettringite treated fibers, aggregates or other fillers can be added to hydraulically settable materials to improve the chemical and mechanical bond between the fibers or other substrates within the resulting hardened hydraulically settable composite material, particularly a cementitious or concrete material

Systems and methods are provided for focused remodeling and downsizing the volume of subcutaneous lipid-rich cells, body contouring, and tightening skin tissue, using controlled heating of the targeted areas on the body. Electromagnetic energy heats skin layers or tissues to achieve an aesthetic effect. The electromagnetic energy may be applied via an applicator without touching the skin. A spacer of insulating or dielectric material may be provided between the applicator and the skin.

Methods and systems for skin treatment

Microparticles having crystalline needle or rod-shaped structures of, for example, an ettringite mineral grown and attached radially from their surface. A method including nucleating and growing crystalline needles/rods from the surface of a particle in the presence of a solution of calcium, sulfur, and aluminum such as calcium sulfoaluminate, lime and calcium sulfate is described. One example is the radial growth of ettringite needles on the surface of fly ash particles in calcium sulfoaluminate-based cement paste and concrete.

This disclosure deals with ettringite whiskers, methods of synthesizing such whiskers and ettringite whisker composites. The ettringite whiskers, having a new crystal form, are 1-2 μm in diameter, 50-100 μm in length and approximately 30-50 of aspect ratio. The ettringite whiskers are especially useful in industry as a high tensile strength reinforcement, they increase self-extinguishability and the productive capacity of making sheets, boards of the like.
