Strength improvement in biopolymer-treated clay: Decoupling the role of densification and bonding
This study presents an experimental framework to isolate intrinsic biopolymer bonding from strength gains induced by densification in stabilized high-plasticity clay. Xanthan gum (XG) and κ-carrageenan (CG) were evaluated using two preparation methods: Method A, in which biopolymer replaces an equivalent soil mass to m...
