What's the average particle size (D50) of Catalpo Clay in this following PhD thesis? Or you can provide the value in other literature. I googled this but found nothing. I have no access to this thesis as well.

Hi, Dong.
D50 (diameter 50%) is a midpoint on the particle size distribution graph meaning that 50% of the particle volume (mass) have size of this particular diameter. It aslo called mass median size. Other parameters and percentage numbers can be used to characterize particle size distribution. For example: P80 - that means 80% of mass smaller than certain size or passing through certain screen mesh - P80=214µm. It may be also R80 - meaning retaining on the screen mesh of certain size.
Hi, Dong.
Very interesting that they provide this information. Thank you. I wonder what would be an application of such general parameter as D50 of a clay?
