The most common organic grinding aids used in the process industry are based on triethanolamine (TEA), triisopropanol amine (TIPA), n-methyl-diisopropanolamine (MDIPA), glycerine, poly-carboxylate ether (PCE), diethyl glycol (DEG) and propylene glycol ( Table 1) [32]. These materials have a number of different functional groups.

4. MECHANISM OF ACTION OF THE CEMENT ADDITIVES Grinding aids have been widely used for more than 50 years. It is also well known that their ultimate target is to prevent cement particle agglomeration during milling process. As a consequence they reduce mill retention time and improve separation efficiency,
