摘要： Exemplary liquid cement additive compositions have high solids loading which includes alkali or alkaline earth metal salts and other cement additive components. The liquid carrier is preferably aqueous in nature, although non-aqueous carriers are possible, and the carrier is modified using a viscosity modifying agent and dispersant to help load salt and other solids in high level amounts. Thus, methods for making the liquid cement additive compositions are also disclosed.

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.

摘要： New set-accelerating admixtures for hydraulic cement compositions are disclosed. These admixtures incorporate set-accelerating compounds and methylol derivatives of amino acids, are found to be surprisingly effective in decreasing the initial set time of hydraulic cements, mortars, and concretes, and are particularly advantageous in reduced-temperature set-accelerators.
