Figure a: Bentonite occurrence map of Afar area (After Tibebu M et.al., 1983). • The second place we took bentonite samples is called Ledi. Ledi is along the main asphalt highway to Addis Ababa to Afar, south of the town of Mile. • The Ledi deposit was less layered than Warsissa deposit and

It is evident from the plots that the bentonite/Ikwo clay dosage increases while the mud samples increased their respective viscosities, which in turn increased the shear stress of the mud (Dankwa et al., 2018). Bentonite/Ikwo clay dosage was varied from 2 to 10 wt% with temperature and mixing time kept constant at 313 K and 35 min, respectively.

bentonite migration, as noted by Gilbert et al. (1996), who describe bentonite migration to the shear plane during laboratory interface shear tests. The presence of wrinkles in an overlying geomem-brane creates zones of non-uniform normal stress, which can cause hydrated bentonite to migrate into the airspace under the wrinkle.
