Sieve Analysis of Fine or Coarse Aggregate with Excel and Pdf File

Sieve analysis is a commonly used method for determining the particle size distribution of a granular material such as fine or coarse aggregate. The process involves passing a sample of the material through a series of sieves of progressively smaller mesh size and measuring the amount of material retained on each sieve.

Here are the general steps for performing a sieve analysis of fine or coarse aggregate:

1. Obtain a representative sample of the aggregate material. The sample should be large enough to provide at least 500 grams of material for testing.
2. Dry the sample in an oven at a temperature of 110 ± 5°C until it reaches a constant weight. This ensures that the sample is completely dry and free of moisture.
3. Weigh the dry sample and record the weight as the initial weight.
4. Set up a series of sieves with mesh sizes ranging from coarse to fine, with the finest sieve at the bottom. The sieves should be stacked in ascending order of mesh size, with a pan placed at the bottom to collect any material that passes through the finest sieve.
5. Pour the dry sample onto the top sieve and cover it with a lid.
6. Place the stack of sieves in a mechanical shaker and shake it for a sufficient amount of time to ensure that all the material has passed through the sieves. The duration of shaking may vary depending on the type of material being tested.
7. After shaking, remove each sieve from the stack and weigh the material retained on it. Record the weight of each sieve as the cumulative weight.
8. Calculate the percentage of material retained on each sieve and the cumulative percentage passing through each sieve and multiplying by 100.
9. Plot the percentage of material retained against the sieve size to obtain the particle size distribution curve.
10. Interpret the results and report the particle size distribution of the aggregate material.

Aggregate sieve analysis is a test used to determine the particle size distribution of aggregates. It involves passing a sample of the aggregate through a series of sieves of decreasing mesh size and measuring the weight retained on each sieve. The results are then plotted on a graph to determine the percentage of material retained on each sieve and the cumulative percentage passing through each sieve.

It is important to follow proper safety procedures when performing a sieve analysis, such as wearing appropriate personal protective equipment and avoiding inhaling any dust or particles.
