During a three-day period, five grinding aid formulations were run on a portland Type I cement using a commercial cement mill. Dilution water was added by rotometer into the feed line, so no pre-mixing for dilution was required. As in Example 1, REAX® G-2 was used as the control grinding aid. The five experimental grinding aid formulations were:
