Laboratory Report –Sieve Analysis
Introduction –Background Information and Purpose
Particle size analysis or sieve analysis is conducted to determine the percentage of
different grain sizes contained within a sample of soil. This analysis is usually done in
accordance with ASTM D422. The purpose of this laboratory experiment is to determine the
particle size distribution graph of a soil sample using sieve analysis. To achieve this, a soil
sample, whose weight has been predetermined, will be passed through a stack of sieves of
decreasing mesh opening sizes. The weight retained on each sieve will then be measured and
recorded. It is vital to note that as the sieve number increases, the size of the openings
decreases.

Methods
To conduct the sieve analysis, approximately 500g of an oven-dry sample of soil was
collected. The sample was then broken into individual particles with the help of a mortar and
a rubber-tipped pestle. The soils sample was set aside, and the weight of each sieve as well as
the bottom pan (Ms) to be used in the sieve analysis was measured and recorded. The weight
of the oven-dry sample (M) was also measured and recorded. The sieves were cleaned, and
the stacks were arranged in descending order with the sieve with large mess opening sizes at
the top and the on sieves with small mesh size openings at the bottom. After arranging the
sieves, the soil sample was poured into the top sieve. The top sieve was then covered with

sieve cover. The stack of sieves was then run through a sieve shaker for about 10 minutes.
After 10 minutes, the sieve shaker was stopped, and the stack of sieves was removed. The
weight of each sieve with its retained soil (Ms+n) was measured and recorded. The mass of the
soil retained on each sieve was calculated using the formula shown below:
𝑀𝑎𝑠𝑠 𝑜𝑓 𝑠𝑜𝑖𝑙 𝑟𝑒𝑡𝑎𝑖𝑛𝑒𝑑
= (𝑊𝑒𝑖𝑔ℎ𝑡 𝑜𝑓 𝑒𝑎𝑐ℎ 𝑠𝑖𝑒𝑣𝑒 + 𝑟𝑒𝑡𝑎𝑖𝑛𝑒𝑑 𝑠𝑜𝑖𝑙) − (𝑤𝑒𝑖𝑔ℎ𝑡 𝑜𝑓 𝑒𝑎𝑐ℎ 𝑠𝑖𝑒𝑣𝑒)
