Advances in geosynthetic clay liners: polymer enhanced clays Universiteit Gent
Bentonite clay is widely used in Geosynthetic Clay Liners (GCLs), because of its elevated sealing capacity in presence of water. However, exposure to high concentrated inorganic solutions can change the clay fabric increasing its hydraulic conductivity. To improve the hydraulic performance of GCLs, a chemical-resistant clay (HYPER clay) was developed through treatment of a natural bentonite with an anionic polymer, Sodium Carboxymethyl Cellulose ...
