Flyash Saturation using CO2

thread261-130209

Flyash Saturation using CO2

Flyash Saturation using CO2

(OP)
I am performing a CU test on Flyash and am having problems achieving B-parameter saturation. Due to the consolidation pressures I can not increase the back pressure and cell pressures further.  I am reading only about 80% B value.  What are the procedures for CO2 saturation? I have a tank of 25% CO2 and 75% Argon I used for welding and was wondering if that would work.  Can I do this even though I have alread been using deaired water up to this point?  I have also run water up thru the sample to help satuation but I am not able to achieve over 80%.  Thanks in advance.
