Gradation of Aggregates Definition. The particle size distribution of an aggregate as determined by sieve analysis is termed as gradation of aggregates. If all the particles of an aggregate are of uniform size, the compacted mass will contain more voids whereas aggregate comprising particles of various sizes will give a mass with lesser voids.The particle size distribution of a mass of ...

Fine aggregate samples or samples of unprocessed mixed-size material from natural deposits sometimes contain a high proportion of fines. The extra fines make handling, sample dividing, and sieving difficult, and needlessly generate a lot of dust. In this case, washing is a matter of convenience and housekeeping.
