Global Cement Grinding Aids Market: Definition and Introduction. The construction industry generates a huge demand for cement. The selection of cement is mainly dependent on efficiency and low cost. Cement grinding aids are used to improve the efficiency of cement production and reduce energy consumption.
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
