Permeability and Disintegration Characteristics of Loess Solidified by Guar Gum and Basalt Fiber

Materials, Journal Year: 2024, Volume and Issue: 17(13), P. 3150 - 3150

Published: June 27, 2024

Loess has the characteristics of loose, large pore ratio, and strong water sensitivity. Once it encounters water, its structure is damaged easily strength degraded, causing a degree subgrade settlement. The sensitivity loess can be evaluated by permeability disintegration tests. This study analyzes effects guar gum content, basalt fiber length on solidified loess. microstructure was studied through scanning electron microscopy (SEM) testing, revealing synergistic solidification mechanism fibers. A model established regression analysis with confining pressure, length. research results indicate that addition reduces loess, improves overall strength, resistance. When content 1.00%, coefficient rate soil are reduced 50.50% 94.10%, respectively. 12 mm, decreases 31.9%, 4.80%. good fitting effect suitable for predicting reinforced composite. vital theoretical worth great scientific significance guidelines practicing engineering.

The Role of Biopolymers on the Water Retention Capacity of Stabilized Sand

Sustainability, Journal Year: 2024, Volume and Issue: 16(19), P. 8612 - 8612

Published: Oct. 4, 2024

The application of biopolymers for sand stabilization has recently gained attention due to their natural composition, which makes them both environmentally friendly and reasonable cost. Measuring the soil–water retention curve (SWRC) biopolymers-treated is essential design, modeling, interpretation unsaturated behavior these materials. Unsaturated shear strength, flow, associated capacity are well addressed evaluated using SWRC. Therefore, this study examined possible effects biopolymers—sodium alginate (SA), guar gum (GG), pectin (P) on SWRC stabilized sand. Apart from sand, three different concentrations were investigated each biopolymer. SWRCs measured over entire practical range suction a combination techniques: hanging column low measurement, axis translation techniques moderate vapor equilibrium technique high measurement. results indicate significant changes in SWRC, new series micropores was developed, this, turn, extends desaturation zone treated (i.e., 30 kPa) levels 10,000 kPa). saturated water content (ws) slightly reduced, air entry values (AEVs), residual (sr) significantly increased multiplied up 200 75 times respectively. increased, exhibiting dependency between biopolymer type range. great significance practitioner engineers researchers predicting soil functions

Study on the Development Rule of Mudstone Cracks in Open-Pit Mine Dumps Improved with Xanthan Gum

Applied Sciences, Journal Year: 2024, Volume and Issue: 14(22), P. 10194 - 10194

Published: Nov. 6, 2024

The stability of open-pit mine slopes is crucial for safety, especially spoil dump slopes, which are prone to cracks leading landslides. This study investigates the use xanthan gum (XG) enhance mudstone in dumps. Various concentrations were mixed with and subjected dry–wet cycle tests assess impact on crack development. Pore analysis system (PCAS) was utilized image recognition analysis, comparing efficiency rate length modification. found that addition significantly improved mudstone’s resistance development post-drying shrinkage. A 2% content reduced by 45% average, while 1.5% 46.2% width 26.3%. Xanthan also influenced fractal dimension water retention cracks. optimal modification identified as between 2%. Scanning electron microscopy imaging X-ray diffraction supported findings, indicating modifies encapsulation penetration wet conditions matrix concentration connection dry conditions. These results expected aid prevention methods engineering applications slopes.
