  • Patent number: 9896387
    Abstract: Compositions and methods for producing a manufactured product, a method for making a liquid absorbent, and processes for disposal of flammable liquids with a flue gas desulfurization by-product. The compositions for the manufactured products combine a binder and the by-product. The composition contains a greater percentage by weight of the by-product than the binder. The methods for producing manufactured products include dewatering the gypsum-depleted waste stream to reduce a water content, and forming the manufactured product. The method for making a liquid absorbent includes dewatering, granulating, drying, heating, and packaging a granulated gypsum-depleted composition as the liquid absorbent. The processes for disposal of flammable liquids include distributing a by-product into contact with flammable liquid, absorbing the liquid, transporting, and igniting the flammable liquid. The artificial soils are a combination of by-product and animal waste, human waste, or another bio-solid.

  • Publication number: 20130145966
    Abstract: Organosilanolate powders having a low cation to silicon ratio provide superior hydrophobing ability. The powders may be prepared on an industrial scale by hydrolysis of a silane with a basic salt solution, adding an inert organic solvent, and removing gaseous or alcoholic hydrolysis products by evaporation or distillation, precipitating the organosilanolate as a fine powder.

  • Patent number: 7097706
    Abstract: The object of this invention is to provide a non-calcined clay composite used as building materials capable of promoting humans' health and being desirably used irrespective of location, which is improved in terms of strength without calcining clay. Because the non-calcined clay composite is produced without calcining clay, the process of producing it is simplified and its productivity is improved. The non-calcined clay composite includes 50 to 90 wt % clay, 2 to 30 wt % lime, 4 to 48 wt % blast furnace slag, 0.04 to 0.9 wt % alkaline chemical, and water as a balance, and has high compression strength due to an ionic coagulation reaction, a pozzolan reaction, and a latent hydraulic reaction.

  • Publication number: 20020017222
    Abstract: A novel construction board composition is disclosed comprising a unique combination of synthetic binders selected for their ability to establish a strengthened permanent bond in the final dry state for use in a construction board composition comprising primarily gypsum, and in a construction board composition comprising an expanded mineral such as Perlite which largely reduces the amount of gypsum over current gypsum construction board formulations, thus reducing the weight while maintaining the strength of the construction board structure. In a preferred embodiment, the lightweight, strengthened gypsum construction board of the present invention also comprises an optional covering veneer that is applied to provide increased strength, moisture resistance, and fire retardency, and the back paper top ply is treated to provide increased flexural strength.
