Introduction
The sieve analysis, commonly known as the gradation test, is a basic
essential test for all aggregate technicians. The sieve analysis
determines the gradation (the distribution of aggregate particles, by
size, within a given sample) in order to determine compliance with
design, production control requirements, and verification
specifications. The gradation data may be used to calculate
relationships between various aggregate or aggregate blends, to check
compliance with such blends, and to predict trends during production
by plotting gradation curves graphically, to name just a few uses. Used
in conjunction with other tests, the sieve analysis is a very good
quality control and quality acceptance tool.
Objective
To determine the particle size distribution of the coarse and fine
aggregates.
Apparatus
 A set of IS Sieves
 Balance or scale with an accuracy to measure 0.1 percent of the
weight of the test sample.
 Mechanical sieve shaker (Optional)
Materials
 Coarse aggregate
 Fine aggregate
Procedure

3. 3
1. The test sample is dried to a constant weight at a temperature of
(110 ± 5°C) and weighed.
2. The sample is sieved by using a set of IS Sieves.
3. On completion of sieving, the material on each sieve is weighed.
4. Cumulative weight passing through each sieve is calculated as a
percentage of the total sample weight.

Discussion and Conclusion
It is evident that sieves can be used to separate both fine and coarse
aggregates into different particle sizes. The number sieves describes
what size aggregate fall through to the next. After the material has
been sieved, we remove each tray, weigh each size, and record each
weight to the nearest 0.1 g, and Ensure that all material entrapped
within the openings of the sieve are cleaned out and included in the
weight retained. After weighting of each sieve samples, we do some
calculations to determine percentage (%) of retained aggregate,
cumulative % agg retained and % agg passing of each sieve.
We conclude that sieve analysis is the simple and easy way to
determine the particle size distribution of aggregate and this sieve
analysis procedure can be used by people who are working in the
laboratory like government laboratory and private independent
laboratory.
