Grinding aids, first introduced into cement manufacturing in 1930, are surface-active substances that facilitate particle comminution during the milling process. In the production of Portland cement, grinding aids are added in small amounts in the range of 0.01 to 0.10% by weight of cement, according to the PN-EN 197-1 standard . They …
