Additive Ö2, a grinding aid, was found to have negligible effect on the strength (for early ages). The fact that additive E is a hydroxylamine-based additive (TEA/TIPA) accelerates the hydration of C 3 S available in the clinker. Similar effect was also observed when additive N was used. As additive Ö2 has a glycol content, it resulted in ...

In mineral beneficiation, grinding is also the most energy~onsuming process. Energy consumed in ore grinding in various mills as compiled by Hartley et al. [2] is shown in Table 1. It is to be noted that the energy consumed in grinding alone represents up to 70% of the energy for the whole beneficiation process (see Table 2 reproduced from a 1934
