Fineness Modulus of Aggregates: The Inside Scoop - Gilson Co.

ASTM C33 requires the FM of fine aggregate to be between 2.3 and 3.1, and that the FM of the final concrete batch cannot vary from the design mix by more than 0.2. Fine aggregate FM’s in the upper end of the spectrum, closer to 3.0, have been noted to produce concrete with good strength and workability in mixes with high cement contents.

Fine Aggregate Angularity - Pavement Interactive

Fine aggregate angularity is important because an excess of rounded fine aggregate (often in the form of natural sand) can lead to HMA rutting. Figure 1: Fine aggregate angularity test. The FAA test estimates fine aggregate angularity by measuring the loose uncompacted void content of a fine aggregate sample.
