Discussion of "Fines classification based on sensitivity to pore-fluid chemistry" by Junbong Jang and J. Carlos Santamarina
(American Society of Civil Engineers, 2017-07)
Atterberg limits of fine soils are strongly influenced by particlefluid interaction phenomena, fluid chemistry, particle mineralogy, and testing procedure (Koumoto and Houlsby 2001). The original paper proposed a very ...
