Hydraulic Performance of Alginate-Based Bentonite
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 discovery of an alternate polymer. Sodium alginate was used to prepare a new, more sustainable polymerized bentonite clay. The alginate was selected due to its recent laboratory extraction from wastewater. This paper presents the performance of the alginate polymer-based bentonite clay in terms of swelling and hydraulic conductivity. Overall, the preliminary results were optimistic towards the use of alginate in polymerized clay. In short, the clay has the potential to be used as an effective hydraulic barrier in the construction industry, which would promote sustainable development.
