Enhancing Freeze-Thaw Resistance in Clayey Soil: Incorporating Jute Fiber and Brick Powder for Sustainable Soil Stabilization
Description
Abstract The study is centered on enhancing geotechnical properties of clayey soil by incorporating jute fiber and brick powder, aiming to optimize its suitability for sub-grade applications. Soil stabilization endeavours to reinforce mechanical attributes, including load-bearing capacity and stability, while simultaneously mitigating risks associated with erosion and degradation. Examining the consequence of freeze-thaw cycles on clayey soil, the study focuses on two key factors: stress-strain characteristics and unconfined compressive strength (UCS).Laboratory experiments involved varying proportions of stabilizers, including jute fiber at 0.2%, 0.3%, 0.5%, 0.75%, and 1%, and combinations of jute fiber and brick powder at ratios of 0.75% + 10%, 0.75% + 20%, and 0.75% + 30%. The overarching aim of stabilization efforts is to minimize settlement, ensuring structural integrity, while simultaneously enhancing resistance to moisture and temperature fluctuations, thereby ensuring sustained stability over time. Significant improvements in UCS were observed across freeze-thaw cycles, particularly noteworthy with the incorporation of 0.75% jute fiber and 30% brick powder. These findings underscore the potential efficacy of employing jute fiber and brick powder in enhancing freeze-thaw resistance within soil stabilization practices. Such promising results offer avenues for the development of more durable and sustainable engineering structures and infrastructure. The integration of jute fiber and brick powder presents a viable strategy for augmenting freeze-thaw resistance of stabilized soil, thereby contributing to advancement of soil stabilization techniques in engineering applications
