3.7 - The fineness and particle size distribution of ...

3.7 The fineness and particle size distribution of Portland cement. The final step in the production of cement is to grind the clinker pellets (and added gypsum) into a fine powder. The resulting individual cement particles have a variety of angular shapes, and a wide range of sizes (see Figure 3-7 below).

F. Fineness Modulus of Aggregate The Fineness Modulus (F.M.) of an aggregate is a numerical index of the relative fineness or coarseness of the aggregate. It is based on th e summation of the percentages of material passing the fineness modulus sieves and is determined by dividing this result by 100, and subtracting from 10.

The information obtained from fineness modulus is helpful in the following ways; Sieve Analysis. 1- Fineness modulus tells us directly whether the material is well-graded or gap-graded. 2- Fineness modulus gives us an overall idea whether the material is fine or coarse. Higher the value of FM,coarser will be the aggregate.
