... resistance of zein biopolymer–treated soil, encompassing three sandy soil types with varying particle sizes. The gelation mechanism of the zein binder is evaluated through rheological and shear wave analyses. Treated and untreated specimens are subjected to hydraulic gradients at constant flow rates...

...Ilhan Chang; Gye-Chun Cho; Thi Phuong An Tran, PhD This study aimed to estimate the effects of the xanthan gum biopolymer on the wetting and drying processes of soils. Xanthan gum with different contents by the mass of dried soil was used to treat Jumunjin sand and sand-clay mixtures. The wetting...
