The resulting value, called the Blaine fineness, is today expressed in units of m 2 /kg, although in previous times it was expressed in cm 2 /g. The Blaine fineness of OPC usually ranges from 300 – 500 m 2 /kg (3000 – 5000 cm 2 /g). It should be noted that the specific surface area is a notoriously difficult parameter to pin down because most materials have features at many different length scales, so that .
