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:
A grinding aid (DEIPA) is a specialty chemical agent used to make it easier to grind and mix cement. Specifically, grinding aids prevent cement particles from re-agglomeration, or re-adhering ...
High performance clinker grinding aids increasing concrete strength through enhanced cement hydration, while simultaneously improving mill productivity and cement quality. Ideal for the production of all types of Portland or blended cements.
