  • Patent number: 11840484
    Abstract: Techniques of forming a foamed insulation material from gypsum waste are disclosed herein. One example technique includes mechanically comminuting the gypsum waste from an original size into particles of gypsum at a target size smaller than the original size and mixing the particles of the gypsum with a binder to form a mixture of particles and binder. The binder is configured to bind the particles of gypsum upon hydration. The example technique can further include performing air entrainment on the mixture until a foam is formed from the mixture having the particles of gypsum and binder. The foam has water that causes the binder to bind the particles of gypsum. The example technique can then include removing moisture from the mixture with the formed foam to form a foamed insulation material from the particles of gypsum.

  • Publication number: 20130263759
    Abstract: Despite the excellent properties associated with Magnesium OxyChloride (Sorel) based cements and Magnesium OxySulfate based cements, water and corrosion resistance has been limiting factors for achieving greater commercial applications. Such issues can be addressed by incorporating various alkali metal phosphates, such as Magnesium mono- or dihydrogen phosphate (MgHPO4 or MgH2PO4) with alkali metal fatty acids; such as Magnesium Stearate; and metal or alkali metal sulfates such as Aluminum Sulfate or Magnesium Sulfate. Water resistance is further enhanced by either pre-carbonating the mix water or the liquid magnesium chloride phase of the cements, or by adding a carbonate into the powder phase. Accelerated cure of this system has also been obtained by using various inorganic metal oxides. Additionally, improved corrosion resistance is achieved through the use of certain phosphates, zeolites, nitrites and other novel additives.
