The 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.
