Cement grinding aid is a kind of chemical additive to improve the grinding effect and performance of cement. In the grinding process of cement clinker, adding a small amount of cement grinding aid can Mineral composition and composition of cement clinker (unit:%). SiO2 Al2O3 Fe2O3 CaO MgO C3S C2S C3A C4AF SiO2 22.41 5.84 3.52 63.24 2.78 39.
A similar trend can already be seen in Table A1: For instance, ultrafine grinding processes demand a significantly higher grinding aid concentration up to several percent related to product mass to achieve the desired grinding aid effects. In contrast to that, lower concentrations between 0.005 and 0.2 wt.% are common for usual dry fine

Figure 426 shows a typical comparison between the grinding of cement clinker with and without a grinding aid. Grachyan and Tavlinova (1973) report that 0.1% of dior triethanolamine increases the
The surface energy of the clinker covered with grinding aid(E) is the algebraic summation of E1,E2 and E3. E= E3 + E2 + E3 1105 Indian Institute of Technology,Delhi 13; 14. If E = ve that means the energy is released and the grinding aid spreads out on clinkers surface.
In summary, conventional grinding aids are used to increase the production rate in the cement mill. If such additions give beneficial chemical effects during hydration of the final cement (e.g. increased strength, improved workability etc.) the grinding aid is regarded as quality improver or performance enhancer.
