Comprehensive understanding of grinding aids

2016-10-2 · 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.
