Assessing cement fineness. In the past, cement producers gauged cement fineness (i.e., cement particle size) by evaluating the specific surface area (SSA) or Blaine fineness and the sieve residue at various sizes. However, many producers now use particle size analysis techniques to assess fineness and help monitor the efficiency of the mill.
