  • Patent number: 9328021
    Abstract: Compositions and methods for increasing grinding efficiency of cement, cement clinker, raw materials for cement, and other inorganic particles. Use of biomass-derived polyols such as diols, triols, or mixtures thereof, optionally with a conventional grinding aid, cement quality improver, and/or hexavalent chromium reducer, are believed to provide less risk of sludging when compared to glycerides obtained from fossil fuel sources.
    Type: Grant
    Filed: March 16, 2015
    Date of Patent: May 3, 2016
    Assignee: GCP Applied Technologies Inc.
    Inventors: Leslie A. Jardine, Charlotte Porteneuve, Gerard Blond

  • Publication number: 20070107638
    Abstract: Methods and compostions of the invention involve the use of crude intermediate fermentation broth, derived from industrial glucose fermentation processes prior to completion of purification steps, as additives and admixtures for cementitious compositions.

  • Publication number: 20070034118
    Abstract: An association complex formed in a liquid environment from a metal-based chromium (VI) reducer and a non-lignosulfonate-based complexing agent is introduced into cement clinker or hydratable cement particles. In preferred embodiments, the formation of the association complex provides storage stability to the chromium reducer within the cement, such that the level of chromium (VI) after water is added to the cement remains less than 2 ppm for certain duration after mixing with water and without the necessity for further additions of chromium reducer during said duration (e.g., 26-84 or more days after addition). Compositions having the association complex are also described.

  • Publication number: 20050096280
    Abstract: Exemplary compositions comprise at least one aldopentonic acid, such as xylonic acid; and further comprise a lignin, a lignosulfonic acid or its salt, an additional sugar acid such as a aldohexonic acid or salt, a conventional admixture (such as a polyacrylate superplasticizer, a corrosion inhibitor, a set retard, a set accelerator, etc.), or a mixture thereof. Exemplary methods for obtaining microbiologically or enzymatically converted sugar acids are also described herein.
