Cement Grinding Additive

Comprehensive understanding of grinding aids - Sika Group

shown that the usual grinding aids and also con-crete additives are well able to withstand normal grinding conditions. Appreciable decomposition is, however, possible if the cement is stored for weeks at above 50 °C temperature. This can occur if silos are filled with hot cement. Mostly adsorption of grinding aids is revers-ible.

Chemical Admixtures - cement.org

Water-reducing admixtures usually reduce the required water content for a concrete mixture by about 5 to 10 percent. Consequently, concrete containing a water-reducing admixture needs less water to reach a required slump than untreated concrete. The treated concrete can have a lower water-cement ratio.
