Sieve Analysis Calculation and Particle Size Distribution (PSD) Plots

Mechanical (or Sieve) analysis is a general term used to define the determination of the size range of particles present in soil/aggregates, expressed as a percentage of the total dry weight. Two methods are generally used to find the particle-size distribution/gradation of soils and aggregates; (a) sieve analysis—for particle sizes larger than 0.075 mm in diameter, and (b) hydrometer analysis—for particle sizes smaller than 0.075 mm in diameter.

How to use this Tool:
1. Input the project and sample details in the respective fields in the 'INPUT - PROJECT & SAMPLE DETAILS' section. The typed in information will reflect in the generated plot and/or the generated pdf report. For more guidance, please make use of the helper text provided below each input cell.
2. Input mass details of the sample in the 'MATERIALS FINER THAN THE SMALLEST SIEVE SIZE (75 MIC (ASTM)/63 MIC (EN)) BY WASHING' section as appropriate.
3. Click on 'Insert Row' button in the 'SIEVE ANALYSIS CALCULATIONS' section to add the required number of rows (corresponding to the number of sieve sizes used in the sieve analysis test) and type in the details of Sieve size and wt.passing in the first two columns.
If the results are to be compared with a reference standard specification, please input the appropriate '% Passing Upper Limits' and '% Passing Lower Limits' values in the last two columns.
4. Click on the 'Calculate & Plot' button. The tool will calculate the 'Cum Wt. Retained', 'Cum Wt. Passing' and '% Passing' and display the results in columns 3 to 5. Simultaneously a PSD plot will also be displayed in the 'PARTICLE SIZE GRADING - CHART' section.
5. The generated particle size distribution plot is interactive and can be zoomed in or out and hovered over for additional data display. The plot can be saved by using the toolbars located on the top right of each plot.
6. Click on the 'Generate Report' button to open up a pdf report in a new tab.
Note: Please make use of the help texts provided in each input cell for further guidance on the usage of this tool.
