Test: Sieve Analysis - Question 1

### The sieve sets for coarse aggregate ranges from:

Detailed Solution for Test: Sieve Analysis - Question 1

According to IS 565, the sieve sets are 80mm, 40mm, 20mm, 10mm, 4.75mm for coarse aggregates.

Test: Sieve Analysis - Question 2

### What is a receiver in a sieve analyser?

Detailed Solution for Test: Sieve Analysis - Question 2

At the base of all the sieve sets, round pan is placed to collect the particles finer than the last sieve size. It is called the receiver.

Test: Sieve Analysis - Question 3

### In how many ways can sieve analysis be carried out?

Detailed Solution for Test: Sieve Analysis - Question 3

The 5 methods are throw-action, horizontal, tapping, wet and air circular jet.

Test: Sieve Analysis - Question 4

Which of the below is a limitation of performing sieve analysis?

Detailed Solution for Test: Sieve Analysis - Question 4

The shape of particles is assumed to be nearly round or spherical so that they pass through the square opening. For elongated, flaky particles it will be difficult.

Test: Sieve Analysis - Question 5

For how long is the mechanical vibrator shaked?

Detailed Solution for Test: Sieve Analysis - Question 5

As per IS code 2720 Part 4. Mechanical vibrator is switched on and allowed to vibrate for 15-20 minutes. It ensures proper grading of particles.

Test: Sieve Analysis - Question 6

The aggregate sample for the sieve analysis is placed on:

Detailed Solution for Test: Sieve Analysis - Question 6

Only if the sample is placed on largest sieve size, it can be sorted, according to each smaller sieve size below.

Test: Sieve Analysis - Question 7

How is percentage retained on each sieve calculated?

Detailed Solution for Test: Sieve Analysis - Question 7

The percentage retained is calculated by dividing weight of sample retained by the weight of the total sample, taken in beginning of test.

Test: Sieve Analysis - Question 8

Under what circumstance is a wet sieve analysis carried out?

Detailed Solution for Test: Sieve Analysis - Question 8

Sometimes samples contain very fine powders which tend to agglomerate. In dry sieve analysis, it would lead to clogging of meshes and it makes analysis difficult.

Test: Sieve Analysis - Question 9

A narrow gradation is also called:

Detailed Solution for Test: Sieve Analysis - Question 9

A graph is plotted after performing sieve analysis. It shows different curves. A narrow gradation is also called uniform gradation. It shows that the aggregate is of approximately the same size.

Test: Sieve Analysis - Question 10

For fine aggregates that is, sample passing through 4.75mm IS sieve, how much sample should be taken?

Detailed Solution for Test: Sieve Analysis - Question 10

IS 2720 gives the specifications. It requires using sample weighing 5 kg for coarse aggregates and 1 kg for fine aggregates.
