Sample Data

Graph 4

Graph No. 4 shows a micro vision of the initial 5 minutes of the test.

All four fluids still show a positive slope which again confirms an immediate

interaction between the clay and the fluid. The fresh water initially showed the

least amount of hydration of the four bases.

The yellow curve of potassium acetate had the highest rate of expansion at

the beginning of the test. After 3 minutes with a 2.5% expansion, the slope

decreased slightly.

After approximately 3 minutes, the fresh water, glycol and the glucose bases

performed equally well, but they began to diverge in a short amount of time at

the 5 minute mark.
