  • Patent number: 7879146
    Abstract: A controlled release formulation for a cement-based composition can be produced by intercalating an admixture (e.g. an accelerator, a set retarder, a superplasticizer) for the cement-based composition into a layered inorganic material (e.g. a layered double hydroxide (LDH)). A cement-based composition containing a cement-based material (e.g. cement, mortar or concrete) and such a controlled release formulation has better workability, especially in respect of slump-loss characteristics. With such a formulation release of an admixture in a cement-based composition may be controlled.

  • Patent number: 7815730
    Abstract: Polymerization of siloxane is improved using a gypsum-based slurry that includes stucco, Class C fly ash, magnesium oxide and an emulsion of siloxane and water. This slurry is used in a method of making water-resistant gypsum articles that includes making an emulsion of siloxane and water, then combining the slurry with a dry mixture of stucco, magnesium oxide and Class C fly ash. The slurry is then shaped as desired and the stucco is allowed to set and the siloxane polymerizes. The resulting product is useful for making a water-resistant gypsum panel having a core that includes interwoven matrices of calcium sulfate dihydrate crystals and a silicone resin, where the interwoven matrices have dispersed throughout them a catalyst comprising magnesium oxide and components from a Class C fly ash.
