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
Sieve analysis helps to determine the particle size distribution of the coarse and fine aggregatThis is done by sieving the aggregates as per IS: 2386 (Part I) – 1963 In this we use different sieves as standardized by the IS code and then pass aggregates through them and thus collect different sized particles left over different siev
