Using a suitable grinding aid, it is possible to manufacture more cement at higher fineness, hence reducing the kWh/t. Their mechanism of action is still unclear, but it is believed to involve the formation of a monomolecular organic layer on cement surface or the neutralization of electrostatic forces formed during breakage of clinker minerals. In this paper we present a study on the effect ...
