Saturation of the sample at triaxial test
Saturation of the sample at triaxial test
(OP)
Hi,
I am doing CU triaxial test on silty sand sample ( sand + 40% low plastic fine content ), I faced with a problem in saturation phase.
I let the Co2 gas goin through the sample about 1 hour then using deaired water, but after 1 day waiting the water does not
move through the sample any more, also I have used cell pressure 2.5 bar and back pressure 2 bar to remove the rest gas in voids, but the sample would not fully saturate.
Would you please suggest me to find the best solution for this problem?

How much your B-value? if it is equal or more than 0.95. That should be ok.

I agree wtih L0k, if the B-value is 0.95, you're there. A B-value of 0.95 does not correlate to 95 percent saturation, it's greater.
