Sieve Analysis of Aggregates

Sieve analysis helps to determine the particle size distribution of the coarse and fine aggregates This 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
