The subject of this paper is to investigate the effect of transition metal oxides on the grindability of clinker. As it is concluded clinker containing ZnO has the lower grindability while clinker containing MnO or Cr 2 O 3 has the higher grindability. The classification of the added oxides, concerning the clinker grindability (descending sort), is: MnO, Cr 2 O 3, Ni 2 O 3, ZrO …
