Get DD Form 1207, Grain Size Distribution Graph - Aggregate Gradation Chart, December 1999

That said, to calculate your distribution curve, you take the total mass of your sample material and divide it by either the weight retained or weight that passed through each sieve, plotting each sieve percentage on the graph.

When you hear the term test sieve analysis results, it is referring to the distribution of particles in a given sample. This can be interpreted by analyzing the retention of particles throughout a sieve stack or the amount of material that passes through each sieve.

Grain size distribution of actual sediment mixture can be roughly classified into three types of distribution, namely, log-normal distribution, Talbot distribution and bimodal distribution, based on the mode of density distribution and indices β and γ.

The two methods generally used to find the grain size distribution are: Sieve analysis which is used for particle sizes larger than 0.075 mm in diameter and. Hydrometer analysis which is used for particle sizes smaller than 0.075 mm in diameter.

When you hear the term test sieve analysis results, it is referring to the distribution of particles in a given sample. This can be interpreted by analyzing the retention of particles throughout a sieve stack or the amount of material that passes through each sieve.

A Particle Size Distribution Curve is printed on the right of the report. You can understand the size distribution from the position of each bar from the chart. From the the inflection point, you can know the major particle size is included in the powder.

Weigh the pan and all of the sieves separately. Pour the soil from above into the stack of sieves and place the cover on it. Put the stack in the sieve shaker, affix the clamps, set a timer for 10 to 15 minutes, and start the shaker. Stop the sieve shaker and measure the mass of each sieve and retained soil.

So I can change that axis x axis to a logarithmic scale.

Sieve analysis determines the particle size distribution of a given soil sample and hence helps in easy identification of a soil's mechanical properties. These mechanical properties determine whether a given soil can support the proposed engineering structure.
