One of the most significant characteristics of ultra-fine cement (UFC) is its high fineness (maximum particle size below 787 μin. [20 μm]). This kind of cement is obtained once ordinary portland cement (OPC) is ground in common grinding devices; the main disadvantages of this type of processing are the long time spent in milling processing …

After 30 h of ball-milling the quantity of ultra-fine particles decreased to 3.5% whereas the quantity of coarser particles increased to 74%. After 6 h of wet ball-milling, 19% of the particles were in the ultra-fine range and 45% of the particles were in the coarser range in the case of the zinc oxide dispersion containing 3 wt.% PCA (Fig. 4).
