バイオマス由来粉砕助剤
Document Type and Number:
Japanese Patent JP5767668
Kind Code:
B2
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 fossils fuel sources.
