Affecting the early-age strength, additive E offers a 2-day compressive strength similar to that of the reference cement. Additives Ö1 and N offer similar 2-day compressive strength patterns. Additive Ö2, a grinding aid, was found to have negligible effect on the strength (for early ages).
Cement grinding aid characteristics. A grinding aid is a surfactant that can improve the grinding environment. The common grinding aid is to improve the grinding effect by improving the viscosity of the material in the mill, the dispersion of the particles and the flow state of the slurry.
Clinker grinding aids. Gypsum is added to clinker primarily as an additive preventing the flash settings of the cement, but it is also very effective to facilitate the grinding of clinker by preventing agglomeration and coating of the powder at the surface of balls and mill wall.
The effect of Grinding Additives is evident in all cases, especially in case of high-Blaine CEM I and blended cements (CEM II as well as CEM III, CEM IV and CEM V cement types). The different grinding processes of vertical mills compared to tubular ball mills, have led to the development of a new generation of Cement Grinding Additives.

shown that the usual grinding aids and also con-crete additives are well able to withstand normal grinding conditions. Appreciable decomposition is, however, possible if the cement is stored for weeks at above 50 °C temperature. This can occur if silos are filled with hot cement. Mostly adsorption of grinding aids is revers-ible.
