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.

Dec 01, 2017· The railroad ballast used in this study was taken from the Bombo quarry located in New South Wales, Australia. It contained primarily augite, feldspar minerals, and plagioclase (Sun, Indraratna, & Nimbalkar, 2014).The physical attributes of the ballast were evaluated by standard testing procedures according to AS 2758.7 (1996) and can be found in Indraratna et al. (1998).

Online Sieve Analysis of Aggregates, Gradation test
A sieve analysis (or gradation test) is a practice or procedure used 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.
