    In practice, portland-limestone cement is ground to a higher fineness compared to portland cement. An increase of Blaine in the range of 100cm2/g is necessary to compensate for the strength reduction resulting from the addition of 1% limestone [3]. The mill type and process system play an important role. Intergrinding (co-grinding) in clas.

    Properties of cement paste were affected significently by fineness of cement which is one of the most important influence factors. Effect of fineness on the rheology properties, strength, hydration and pore structure of cement was studied. The results showed that: plastic viscosity of the cement paste can be reduced by the increase of cement fineness to some extent.
