Thereby, the grinding aid effects were found to be very solid-specific. For the fine grinding of limestone, slag sand and quartz, the addition of comparatively high amounts of heptanoic acid caused the most pronounced stabilization effects. Generally, the grinding aid effects were lower in the case of quartz in comparison to the other materials.

Benefits of Cement Grinding Aid; CGA reduces the inter-particle attractive forces of cement which causes agglomeration of cement grains. CGA are adsorbed on the newly created surface, neutralising electrical charges and thus reducing their tendency to re-agglomerate. Hence, the cement grains show a lower resistance to comminution.
