Hello everyone,
I had a really important problem and performed an extensive literature search, however, I couldn't find anything except few articles.
My problem is: Sand's permeability.
We all -I think- sand settles almost immediately due to high permeability. Howewever, in a project, I had a chance to get UD from clayey sands and oedometer test yields very low permeabilities although sand ratio is around 75% and clay is around 15-20%.
When I looked it up, I found an article that performed consolidation tests on different sand-clay ratios. I saw that even 10% clay ratio is decreasing permeability to 10-8 m/s.
What experience do you have on this issue? Do you have any resource? I really don't want to say there is a time-dependent settlement in sands, however, it seems like that. I would like to discuss this issue and waiting any contribution from you guys.
Thanks.
