BIOMASS-DERIVED GRINDING AIDS |
摘要 |
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. |
