(OP)
Hello,
Is it possible to measure pore pressure during an Unconsolidated Undrained Triaxial Test?

You could do a UU test in some stress path equipment (i.e. the equipment in which you'd do consolidated undrained triaxial testing) and be able to measure the PWP response as standard, though I'm not sure why you'd want to do that: if you're going to the effort to measure PWP then you ought to do a consolidated test and get a representative response; the UU test will likely not give you a representative PWP response.
Why do you require the PWP response from a UU?

I thought to ask that if youre going to measure PWP why dont you just to a CU test? for the sake of the extra day?
Interested to hear opinions, do other people adopt/agree with the above?

Anyways, I also have little lab experience with TX tests but I tend to agree with EireChch - if you want to measure PWP, I would go for CU tests.
