  • Sieve analysis - Wikipedia

    A gradation test is performed on a sample of aggregate in a laboratory. A typical sieve analysis involves a nested column of sieves with wire mesh cloth (screen). See the separate Mesh (scale) page for details of sieve sizing.. A representative weighed sample is poured into the top sieve which has the largest screen openings.
