Abstract: The effect of additives A,B and C on grinding ordinary Portlandcement,slag cement and fly-ash cement was studied in this paper. The results show that the additives A,B,C have a remarkable effect on increasing fineness of cement, decreasing the angle of repose of power and improving flowability of materials,which may increase grinding efficiency. At the same time,for different materials,such as slag and fly-ash,the grinding mechanism is different.
