[email protected]A sieve analysis or gradation test is a practice or procedure used to assess the particle sie distribution also called gradation of a granular material by allowing the material to pass through a series of sieves of progressively smaller mesh sie and weighing the amount of material that is stopped by each sieve as a fraction of the whole mass

It is calculated by performing sieve analysis with standard sieves. The cumulative percentage retained on each sieve is added and subtracted by 100 gives the value of fine aggregate. Higher the aggregate sie higher the
