Numerical on Sieve Size Analysis: Plotting Semi Log Graph: Particle-Size Distribution Curve

Link for the Numerical solution: drive.google.com/file/d/1XzR7...
Sieve analysis consists of shaking the soil sample through a set of sieves that have progressively smaller openings. The results of sieve analysis are generally expressed in terms of the percentage of the total weight of soil that passed through different sieves. The results of mechanical analysis (sieve and hydrometer analyses) are generally presented by semi-logarithmic plots known as particle-size distribution curves. The particle diameters are plotted in log scale, and the corresponding percent finer in arithmetic scale. As an example, the particle-size distribution curves for two soils are shown in this numerical.

Good work, nice explanation!!

[@DawaStories]

Thanks alot, u made everything clear

[@ogwalemmanuel2140]

You helped me pass my last semester papers. Thanks

[@CuriousCivilEngineer]

Glad I could help. Best of luck ahead.

[@kazimonir5808]

Thanks a million

[@enjoylifewidcgl7141]

Thank you so much

[@shadmansakib3636]

thank you sir

For sieve number 100 which is 86g percent retained is supposed to be 13.94% sir

[@kethavathchandunayak7123]

If for a particular soil three samples are tested and three values are given then how you decide the soil type...( Note same soil but three diffeeent test results)

[@CuriousCivilEngineer]

Please look at Indian standard classification of soil. Soil types depends upon their grain sizes. If more than 50% soil is retained on 0.075 mm sieve, then it's a course grain soil. If more than 50% is passing through 0.075 mm sieve then it's a fine grain soil. If it's a course grain soil and more than 50% is passing 4.75 mm sieve then it's a Sand else it's a gravel. Fine grain soil can also be classified based upon plasticity chart. I will make a video about next week.

can someone enlighten me on how did he interpolate the values of D10, D30, and D60?

[@wasimshaikh1665]

Hey hi. You just draw a horizontal line (shown in red) from 10% on Y axis till it meets your curve. Once it meets the curve, you can draw vertical line till it meets X axis. Where ever it meets X axis, that's your value of D10. Same thing you repeat for D30 and D60.
