Abstract:
This test is performed to determine the percentage of different grain sizes
contained within a soil. The mechanical or sieve analysis is performed to
determine the distribution of the coarser, larger-sized particles, and the
hydrometer method is used to determine the distribution of the finer particles.

Introduction :
- Determination of article size is more important in Civil Engineering, as the particle size
determines the effectiveness of final product. The characters of particle such as bulk
density, physical stability, permeability and many more are decided by its size. To
determine the size distribution of particles, the sieve analysis test procedure is an
effective method that prevailed from the past. 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.
Depending on the needs and particle material different sieving methods are available
for the application. They are manual sieving method, mechanical sieving method, dry
sieving method and wet sieving method.
Objective:
- The only objective we have in this experiment or the main objective is to determine a
particular soil grain size distribution.
10. If a considerable amount of soil with silty and clayey fractions is retained
on the No. 200 sieve, it has to be washed. Washing is done by taking the
No. 200 sieve with the soil retained on it and pouring water from a tap in
the laboratory (Fig. 4.2).
Results and sample of calculation:
- The results should be calculated and reported as the cumulative percentage by
weight of the total sample and the percentage by weight of the total sample passing
through one sieve and retained on the next smaller sieve, to the nearest 0.1 percent.
The results of the sieve analysis may be recorded graphically on a semi-log graph
with particle size as abscissa (log scale) and the percentage smaller than the
specified diameter as ordinate.
- Calculation:
- Percentage of soil retained on nth sieve (counting from top):
𝑛
2. Cumulative percentage of soil retained on the nth sieve:
3. Cumulative percentage passing through the nth sieve:
Discussion and Conclusion:
- In conclusion the experiment was done according to the procedure and the right steps
were taking but as seen in the result there are errors that will be discussed below. The
experiment overall was a success the objective and theory was reached.
Errors and Problems:
- As error I as the writer of this report wasn’t present during the experiment that can be
considered a problem. As shown in the resilt table there is an error and it can be
caused by the sieves not cleaned probably leaving some aggregate leftover from
previous experiment or that the sieves are old and rusty.
