Sieve analysis - Wikipedia

A sieve analysis (or gradation test) is a practice or procedure used in civil engineering and chemical engineering to assess the particle size distribution (also called gradation) of a granular material by allowing the material to pass through a series of sieves of progressively smaller mesh size and weighing the amount of material that is stopped by each sieve as a fraction of the whole mass.

Particle Density - an overview | ScienceDirect Topics

The possible apparent particle density values for normal United Kingdom aggregates range between 2.4 and 3.0 Mg/m 3 but the majority are in the narrow 2.5–2.7 band (Table 15.8).Aggregate particle density usually is not directly related to concrete performance in the materials sense, but might be relevant from a structural standpoint (e.g. gravity structures).
