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.

Aggregates MCQ [Free PDF]
If aggregate remain on 4.75 mm sieve then they are called coarse aggregates. i.e. Coarse aggregate > 4,75 mm. If aggregates pass through 4.745 mm grade and retain on a 75-micron sieve then they are called fine aggregates. i.e. Fine aggregate 4.75 mm Note: For RCC work, the maximum size of aggregate is limited to 20 - 25 mm

Construction aggregates: evaluation and specification
The proportion of material passing a 2.36mm sieve is the AIV (mean value of two tests). The lower the AIV the stronger the aggregate. It is a simple, cheap test giving precise results. An AIV less than 30 is usually required. Aggregate Crushing Value (ACV) – this is the measurement of the resistance of aggregate to crushing by compressive force.
