  • Biomass derived grinding aids
    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
