Sieve Analysis of Aggregates
Sieve analysis helps to determine the particle size distribution of the coarse and fine 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 sieves.
