Biopolymers have been widely experimented with as organic stabilizers in the last decade for improving soil properties. However, high nutritional value of some biopolymers like chitin, carrageenan, casein, and chitosan can also promote microbial growth which affect improvement strength biopolymer-stabilized soil. This study investigates mechanical behaviour clay treated at dosages 0.5, 1.0, 1.5, 2.0% various curing periods 7 d, 28 56 90 d observes fungal growth, conditions favourable to effect an inorganic secondary additive on The shows that is higher time dosage chitosan. chitosan-treated samples increased both age despite observed soil, did growth.

This study aimed to evaluate the influence of indirect-plasma-treated water (IPTW) in preparation hydrogels. Three commonly used natural, biodegradable polymers with ability form gels were selected: gelatin, carrageenan, and sodium alginate. The pH, gelling temperature, texture profile, swelling degree, color hydrogels evaluated, subjected Fourier-transform infrared (FTIR) spectroscopy. morphology was investigated using Scanning Electron Microscopy (SEM). Additionally, physiochemical properties media, which distilled (DW) IPTW, analyzed. results indicated that prepared IPTW characterized by a lower higher hardness gelation temperature. After 48 h ratio (SR) testing, gelatin alginate made SR, while an inverse relationship found case SR carrageenan gels. FTIR analysis confirmed changes binding ability. use also significantly affected microstructure tested materials. A statistically significant change gel samples noted. showed induces physicochemical hydrogels, can lead enhancement their practical applications.

As is widely accepted, cumulative strain and improvement mechanisms of stabilized soil are critical factors for the long-term reliable operation expressways high-speed railways. Based on relevant research findings, xanthan gum biopolymer regarded as a green environmentally friendly curing agent in comparison to traditional stabilizers, such cement, lime, fly ash. However, little attention has been devoted reinforced by under traffic loading. In current study, series laboratory tests, including cyclic triaxial tests scanning electron microscopy (SEM) were performed investigate this issue more detail. The influences content, time, moisture confining pressure, stress amplitude analyzed. addition, model was proposed provide good description experimental data. Finally, microscopic structure analyzed discuss mechanisms. results show that strongly influenced content. For given number loading cycles, greater smaller strain. calculated agreement with test “flocculent” hydrogel can form denser bonding strength “branch-like” “net-like” hydrogels.
