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. These provides benefits to grinding efficiency by
