MoreThe fineness of a portland cement is a key factor in determining its strength development characteristics. A simple one-parameter fineness characterization such as a Blaine value or a sieve residue is often inadequate for a precise evaluation of the influence of fineness on the strength development of cement, especially when comparing cements ground with different grinding equipment.

MoreA particle size distribution indicates the percentage of particles of a certain size (or in a certain size interval). These intervals are also called size classes or fractions. A simple example is shown below. Here, a mixture of grinding balls has been separated by size: 5
