What Is Sieve Analysis Test?

Important Point

Sieve analysis, often referred to as sieve analysis of aggregate, is an analytical technique used to determine the particle size distribution of granular material with macroscopic granular sizes.

This sieve analysis technique, crucial for both sieve analysis of coarse aggregate and sieve analysis of fine aggregate, 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.

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.

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.

FAQ

Sieve Analysis Test

A sieve analysis or gradation test determines the distribution of aggregate particles by size within a given sample. This information can then be used to determine compliance with design and production requirements.

Particle Size Analysis by Sieving

In sieve analysis, the particle size distribution is defined using the mass or volume. Sieve analysis is laboratory test procedure in which particles will move vertically or horizontally through sieve mesh.

Particle Size Distribution Test

A Particle Size Distribution Analysis (PSD) determines and reports information about the size and range of particles representative of a given material. This analysis can be performed using a variety of techniques; the most suitable will be determined based on the sample properties and question at hand.

Soil Gradation Test

Soil gradation test is a practice or procedure used commonly used in civil engineering 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.

Why Gradation Test Is Done?

How Do You Do a Grain Size Analysis?

The test is conducted by placing a series of sieves with progressively smaller mesh sizes on top of each other and passing the soil sample through the stacked sieve “tower”. Therefore, the soil particles are distributed as they are retained by the different sieves.

Particle Size Distribution Test Procedure

Particle size distribution is determined by weighing the material retained on each of the sieves and dividing these weights by the total weight of the sample. A correction is made for the moisture content of the sample so that all calculations are based on dry weight.

Grain Size Analysis

Grain size analysis is a typical laboratory test conducted in the soil mechanics field. The purpose of the analysis is to derive the particle size distribution of soils. Sieve Grain Size Analysis is capable of determining the particles’ size ranging from 0.075 mm to 100 mm.

What Is the Purpose of Grain Size Analysis?

The grain size analysis is widely used in classification of soils. The data obtained from grain size distribution curves is used in the design of filters for earth dams and to determine suitability of soil for road construction, air field etc.

Particle Size Distribution Curve Sieve Analysis

The results of mechanical analysis (sieve and hydrometer analyses) are generally presented by semi-logarithmic plots known as particle-size distribution curves. The particle diameters are plotted in log scale, and the corresponding percent finer in arithmetic scale.
