Several fly ash cements have been reproduced in lab ball mill by grinding the same composition (65% clinker, 5% gypsum, 30% fly ash) without any gri nding aid (blank) and with different grinding aids. A glycol based grinding aid has been used to check the effect of fineness increase, so the same grinding time this means same energy consumption has been .

Lethabo fly ash < 1,0 % and Matla fly ash < 2,5 %. Finally a word of caution with regard to optimum grinding time: the findings from an experiment in a laboratory mill cannot be directly related to the performance of an industrial mill, especially a closedcircuit mill with a highefficiency separator attached. reSPoNSe froM the AuthorS
