sieve analysis of aggregates - civil engineering
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.
