Sep 01, 1999  For the influence of the aggregate size grading, two kinds of aggregate were used. The aggregate of the 0.15–0.80-mm range is a fine aggregate, and that of the 5–10-mm range is a coarse one. Under the condition that the property of mortar is constant, the different amount of coarse aggregate was added and the expansion was observed.

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.
