Fineness of Cement by Blaine’s Air Permeability test
WebWhile regular portland cement contains up to 5% limestone, PLC is a finer-ground product than regular portland cement. Limestone is softer and finer than clinker, with limestone being ground to an estimated 6 microns and cement ground to 15-20 microns. The Blaine fineness of PLC Type IL, although not a perfect measurement WebJun 17, 2024 · 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.
