Comparison between grinding of cement clinker with and without grinding aid (after Fuerstenau, 1990) Figure 1 shows the typical comparison between grinding of cement clinker with and without a grinding aid in a laboratory mill. As discussed in the literature [1,2,4], there was significant effect of using grinding aid in cement grinding.

Di ethylene glycol is also used as a chemical intermediate in the manufacture of unsaturated polyester resins, plasticisers, acrylate and methacrylate resins, and urethanes. In the U.S. and Western Europe 51% of DEG is consumed in this way. However, in Japan it is most utilised as a cement grinding aid.

Additive compositions for use as grinding aids and pack set inhibitors in the manufacture of hydraulic cement composed of a water-soluble polyol, particularly a glycol, and a water-soluble salt of an aliphatic acid having no more than three carbons, said additive compositions being used either alone or in combination with water-soluble salts of a sulfonated lignin, a water-soluble …

Results of the grinding aid tests, including comparisons with ethylene glycol (a known grinding aid) appear in Table 1. EMI4.1 As is shown by the above example, a grinding aid according to the present invention, when added to a Portland cement clinker, increases grinding efficiency over the clinker alone ("blank") as well as a known, chemically ...
