Sieve Analysis Test of Sand

Sieve Analysis Test of Sand – Procedure & Result

Sieve Analysis Test of Sand is done to check the gradation of sand particles. Sand particle distribution in sand volume is important for good quality concrete and mortar.

In this test, the sand sample is passed through a series of IS sieve sizes ordered from bigger to a smaller size at the bottom. A sand particle having respective size retained on a sieve and then the weight of sand retained on each IS Sieve taken.

Then % of sand retained on each IS Sieve is calculated which shows the particle size distribution in the sand sample.

Aim:

To determine the Particle Size Distribution of Sand Sample.

Apparatus for Sieve Analysis Test:

  • Sieves as per IS standards (sieve 10mm, 4.75mm, 2.36mm, 1.18mm, 600µ, 300µ, 150µ)
  • Mechanical sieve shaker
  • Dry oven
  • Weighing scale

Test Procedure:

1) Take the required amount of aggregate sample (for a sand (fine aggregate) minimum of 0.5kg sample is required.

2) Arrange the required no of sieves as per the contract or job requirement in a descending manner. (i.e. keep the sieve having the largest size opening at the top and the smallest size opening at the bottom)

Sieve Arrangement – At Top 10mm , 4.75mm, 2.36mm, 1.18mm, 600µ, 300µ, 150µ at Bottom and Last Pan)

3) Place the sieve set on the mechanical shaker and shake vigorously for at least 2 minutes.

4) Then measure the weight of aggregate retained on each sieve and express it as the percentage of passing.

5) Now compare these values with the recommendation values to know whether it falls within the range or not. If not comes within the desired gradation, then take the necessary action to make sand well graded.

6) The grading limit of sand (fine aggregate) is given below.
