CE 531 Mod 2.1.2: Clay-Water Interaction

[@TheAncientColossus]

I wish we could get the link for the video described at 25:29 about ion concentration increase in quick clay. How does the clay "get thick again" if the double layer is decreasing? Shouldn't it be shrinking if it's losing thickness? One can only dream.

exactly what i was looking for , i also believe you made a mistake at 39:20 its gibbsite not SiOH

I've read that a higher zeta potential results in higher stability and repulsion of clay colloids. However, in this video, an increase in ion concentration results in a higher zeta potential but decreases the double layer thickness. How does this mean that the clay is expansive? Can someone please elaborate? I realize that there are not many viewers but I hope I can find a Geotechnical mentor one day!

@Jonah Justus I really appreciate your reply. I got to the site through google and im trying it out atm. I see it takes quite some time so I will reply here later with my results.

@Jonah Justus It worked and I actually got access to my account again. I am so happy:D Thanks so much you saved my account :D

@Darwin Ellis Happy to help xD

A question please i cant understand why as the CEC increases the water layer becomes smaller i think this more cations will attract more water to it and swelling potential also increase

I asked a similar question 6 months ago. No one seems to know. Someone please help...
