Fineness factor
WebFineness indicates the fineness or coarseness degree of powdery materials. It is often expressed as standard sieve percentage or specific surface area. Fineness can also be expressed by percentage of particles of various sizes or average value of unit weight material. The population of particles of various sizes is termed as particle size ...

Ordinary Portland cement (Types … WebA standard parameter to express the size of molding sands is the AFS fineness number (AFS = American Foundry Society). This number is calculated from the size distribution, which is determined by standard ASTM sieves. Each fraction is multiplied with a weighting factor, the results are added together and divided by 100.

Ordinary Portland cement (Types I and II) has a surface area between 3000 and 3500 cm 2 /g, while the surface area for rapid hardening Portland cement (Type III) ranges from 4000 to 4500 cm 2 /g.
WebThe finesse of an optical resonator ( cavity) is a measure for how narrow the resonances are in relation to their frequency distance: a high finesse means sharp resonances. It is defined as the free spectral range (i.e., the fundamental mode spacing) divided by the (full width at half-maximum) bandwidth of the resonances.
WebThe fineness factor is based on dry sieving and the purity is determined by comparing the sample to pure calcium carbonate. In most cases, byproduct liming materials cannot be testing using the conventional methodology due to the presence of clumps or aggregates making it impossible to sieve the sample.
