Years of cement production practice shows that cement particle gradation should be distributed continuously within a certain size range. Generally speaking, the cement particles smaller than 32 m are beneficial to reduce bleeding and early strength, but as the size of particles gets smaller, although the hydration activity increases, the voidage of particles will also increase when they ...

2020-5-18Assessing 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.
