The modulus of fineness is typically used to determine the aggregate’s coarseness or fineness. When the fineness modulus value is higher, the aggregate is coarser, and when it is lower, the aggregate is finer. These solid brass sieves are a full eight inches in diameter and are the same type of sieves used by laboratories and universities for particle size analysis. AASHTO The Voice of Transportation. T0 27. (2006). http://bookstore.transportation.org/item_details.aspx?ID=659

The values are then plotted on a graph with cumulative percent passing on the y axis and logarithmic sieve size on the x axis. [6]

The size of the average particle on each sieve is then analysed to get a cut-off point or specific size range, which is then captured on a screen. Solutions are a mixture in which a solid or a gas has completely dissolved in a liquid. We called the solid a solute and the liquid a solvent. A solid that will not dissolve in a specific liquid is described as insoluble. Woven wire mesh sieves are according to technical requirements of ISO 3310-1. [9] These sieves usually have nominal aperture ranging from 20 micrometers to 3.55 millimeters, with diameters ranging from 100 to 450 millimeters.

W Below - The total mass of the aggregate within the sieves below the current sieve, not including the current sieve's aggregate. Additionally, it accurately describes the workability of the concrete, which is determined by the slump value. The compressive strength and density of the finished concrete are both fundamentally governed by the modulus of fineness.
