What Is Sieve Analysis Test

What Is Sieve Analysis Test?

Sieve analysis is an analytical technique used to determine this particle size distribution of granular material with macroscopic granular sizes. This sieve analysis technique involves the layering of sieves with different grades of sieve opening sizes.

This finest sized sieve lies on the bottom of the stack with every layered sieve stacked above in order of increasing sieve size.

When a granular material is added to this top and sifted, the particles of this material are separated in the final layer the particle couldn’t pass.

Commercial sieve analyzers weigh every individual sieve from the stack to determine the weight distribution of these particles. This base of this instrument is a shaker, which facilitates the filtering.

Sieve analysis is important for analyzing materials because particle size distribution may affect a wide range of properties, like the strength of concrete, the solubility of a mixture, surface area properties, and even their taste.

Procedure Sive Analysis Test for Coarse Aggregate:

• A sample of aggregate shall be collected as given earlier.

• Sieves shall be cleaned and arranged in sequence in descending order. Pan shall at the lowermost end and Lid on top.

• Take around 5 kg of sample and dry it in an oven at a temp of 100-1100

• The dried sample shall be then weighed ( 5 kg preferably) and sieved successively on sieves starting with 40mm and then through 4.75mm (For 20 mm down an aggregate size ) and through 2.36 mm (For 12.5/10 mm down an aggregate size).

• Each sieve shall be shaken at least for two minutes on a clean tray until no more trace passes.

• The motion shall be varied like back and forth, left to right, circular clockwise and anti-clockwise and with frequent jarring.

• Material shall not be forced through the mesh. But for coarser than 20mm particles, placing is permitted (passing particles through sieve opening manually).

• Sieves shall be brushed from underneath of mesh and pass on to the next.

• On completion of sieving, material retained on each sieve is to weigh Separately.

• Check for permissible limits for passing.

Procedure Sive Analysis Test for Fine Aggregate:

A sample of sand shall be collected as given earlier.

Sieves shall be cleaned and arranged in sequence in descending order. Pan shall at the lowermost end and Lid on top.

Take around 1 kg of sample and dry it in an oven at a temp of 100-1100

The dried sample shall be then weighed ( 1 kg preferably) and sieved successively on sieves starting with 10mm and then through 150 microns.

Each sieve shall be shaken at least for two minutes on a clean tray until no more trace passes.

The motion shall be varied like back and forth, left to right, circular clockwise and anti-clockwise and with frequent jarring.

Material shall not be forced through the mesh. Lumps in fines shall be broken against the wall of a sieve.

Sieves shall be brushed from underneath of mesh and pass on to the next.

On completion of sieving, material retained on each sieve is to be weighed separately.

Calculations of Sive Analysis Test for Fine Aggregate:

Fineness Modulus: Add values of Cumulative % Retained on each sieve and  Divide by 100.

• Normally the accepted limit of FM is valued between 2.2 to 3.2. 

A higher value of FM indicates coarser sand, whereas lesser value indicates a finer one.

• Grading Zone of Fine Aggregate – Value is shown between I to IV.

Where zone- I is associates with Coarser Fine aggregate, and Zone IV is Finer.

Zones are decided from values of 600 microns passing % in sieve analysis. (Refer Table-4 of IS: 383)

Zone –I – 15-34%, Zone-II – 35-59 %, Zone-III- 60-79%, Zone-IV- 80-100%

Reporting:

The cumulative % by weight of the total sample passing each sieve, to the nearest whole number.

Or

The % by weight of the total sample passing one sieve and retained on the next smaller sieve to the nearest 1 decimal. Calculate the F.M. of the material and decide to read the Zone of material.
