Saturation times
- Thread starter OCclay101

are you using backpressure? If you maintain 5psi of effective stress (sigma 3 minus backpressure), you can increase the cell and backpressure simultaneously and get the air in the voids to go into solution. The b-value is used to evaluate the extent of saturation.

Yes I was going to saturate by maintaining a small effective stress and increasing the cell pressure and back pressure and using the B-value to check. I am broadly using the BS1377 methodology. No-one here has done this before so really don't know how long it will take. Samples have permeability between 1e-9 - 1e-11. I have read a thesis by Gasparre 2005 who deals with similar material but no time is specified.
