It appears that WFT2, containing 7 phr more DC-40C,
swelled significantly less and slower than WFT1, as shown in figure 3.
The mechanisms of water diffusion into the
swelled hydrogel were investigated by (4).
The swell pressure of the specimen was determined by loading the
swelled specimen in various increments (Sridharan et al., 1986).
At the initial moist content of 20% the soil
swelled rapidly, whereas at the higher moist content the swelling rate was much slower.
By the time I got there the other side of my face had
swelled up too.
My ankle
swelled to size of my calf, and I was in a boot for two months.
According to the results given in Table 1, the SLIG samples after three swelling measurements
swelled reversibly, and the height of dry bed of coal samples did not change due to re-swelling.
