7. Precautions in Sieve Analysis a. During sieve analysis, sieve should be shaken in the rotation rather than translating linearly. b. To sieve, the small mass should be used each time for better sieving. 8. Advantages of Sieve Analysis a. It helps to determine the size of particles and fineness of aggregates. b.

(3) Calculate the percent passing (or percent finer) by starting with 100 percent and subtracting the percent retained on each sieve as a cumulative procedure. For example: Total mass = 500 g . Mass retained on No. 4 sieve = 9.7 g . Mass retained on No. 10 sieve = 39.5 g . For the No.4 sieve:

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.

Sieve Analysis Overview Sieve analysis is a technique used to determine the particle size distribution of a powder. This method is performed by sifting a powder sample through a stack of wire mesh sieves, separating it into discrete size ranges. A sieve shaker is used to vibrate the sieve stack for a specific period of time.

The most important requirement for a reproducible sieve analysis is to obtain a representative partial sample from the whole of the bulk material to be tested.
