Amine and glycol-based grinding aids (GA) were incorporated at various concentrations of 0.04, 0.06, and 0.08% of the cement weight. At Ec values lower than around 20 kWh/ton, test results have shown that cement fineness increases almost linearly with the increase in grinding energy according to Rittinger’s law.
