Relatively coarse sand has a lower binder demand than a finer one, but a coarser surface finish may result. Expressed as either: AFS, which is the grain fineness index, the higher the number, the finer the sand e.g. 50, 60, 70, 80 AFS or as AGS, average grain size in microns, the higher the number, the larger the particles e.g. 120, 140, 160 AGS.

 · Table 2 shows a comparison of two sands that have the same AFS-GFN but different distributions. Sand A is a 5-sieve sand because 10% or more of the sample was retained on each of five adjacent sieves (40, 50, 70, 100 and 140). Sand B is a 3-sieve sand because 10% or more was retained on each of only three adjacent sieves (50, 70 and 100).
