Sieve analysis Wikipedia

A sieve analysis or gradation test is a practice or procedure used commonly used in civil 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
