7. Precautions in Sieve Analysis a. During sieve analysis, sieve should be shaken in the rotation rather than translating linearly. b. To sieve, the small mass should be used each time for better sieving. 8. Advantages of Sieve Analysis a. It helps to determine the size of particles and fineness of aggregates. b.

A sieve analysis (or gradation test) is a practice or procedure used 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.

A variety of methods are used to evaluate materials for an aggregate base. The size and gradation of aggregate particles is determined by sieve analysis. For proper gradation, this should be performed with washed aggregate material, as dry sieving can produce erroneous results due to fine material sticking to the surfaces of larger particles.
