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...

In this case, washing is a matter of convenience and housekeeping Coarse aggregate samples may not require a P200 determination at all, but it still may be helpful to wash them On the other hand, an accurate P200 value may be an important focus of the requested gradation tests, especially with fine aggregate specimens...
