  • Performance Enhancer for Portland Limestone Cement (PLC)

    In practice, portland-limestone cement is ground to a higher fineness compared to portland cement. An increase of Blaine in the range of 100cm 2 /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.
