- D10
- Mean:
- 34.85 µm
- St. dev.:
- 1.91
- Percentile:
- D50
- Mean:
- 142.95 µm
- St. dev.:
- 5.87
- Percentile:
- D90

- Conclusions:
- The size distribution of this sample, in our experimental conditions, is characterised by an Equivalent Circle average median particle size by volume of 143μm and an Equivalent Circle average volume mean of 166.9μm.
- Executive summary:
The particle size distribution of the sample is determined by static image analysis provides by an optical microscope.
The size distribution is expressed in Equivalent Circle in volume. This kind of result can be directly compare to laser granulometry result.
The size distribution of this sample, in our experimental conditions, is characterised by an Equivalent Circle average median particle size by volume of 143μm and an Equivalent Circle average volume mean of 166.9μm.
