Hydraulic Performance of Alginate-Based Bentonite

Geo-Congress 2022, 2022
Bentonite clay is widely used as a hydraulic barrier in geosynthetic clay liners and cut-off walls. The interaction of the clay with divalent electrolytic solutions such as Ca2+ or Mg2+ deteriorates its sealing properties. The treatment of bentonite with polymers has improved its hydraulic properties; however, sustainability concerns have led to the ...
