Use of cement grinding aids to optimise clinker factor ...
The tested cement properties include water demand, Blaine fineness, sieve residue, setting time and compressive strength. The results showed that the use of higher concentrations of GAs can lead to significant improvements in the performance of grinding mills characterised by higher Blaine and lower sieve residue values.
Comprehensive understanding of grinding aids
the industrial grinding of cement, even without the use of grinding aids. Therefore it can be assumed that the surfaces of the majority of commercial clinkers are predominantly or even completely hy - droxylated. This is also important because it as-sists the grinding, in other words water is a weak grinding aid. The chemical reaction of oxide ions
