Area Of Science
- Geotechnical Engineering
- Materials Science
- Environmental Science
Background
- Sulfuric saline soils in arid regions pose significant engineering challenges.
- Existing stabilization methods may lack environmental sustainability.
- Eco-friendly reinforcement materials are needed to improve soil performance.
Purpose Of The Study
- To investigate the mechanical properties and micromechanisms of sulfuric saline soil reinforced with natural fibers.
- To evaluate the effectiveness of various natural fibers (rice husk, jute, sisal, palm, coconut shell) and their contents on soil stabilization.
- To assess the impact of fiber reinforcement on soil strength, density, and resistance to degradation.
Main Methods
- Experimental analysis including unconfined compression tests, shear strength tests, and micromorphology analysis (SEM, NMR).
- Evaluation of optimum moisture content (OMC) and maximum dry density (MDD).
- Wet-dry cycle tests and dissolution coefficient analysis to assess durability and saline resistance.
Main Results
- Natural fiber incorporation significantly enhanced unconfined compressive strength (UCS) and shear strength.
- UCS increased by up to 2.8 times with jute fiber and 2.48 times with sisal fiber.
- Fiber reinforcement improved resistance to strength loss during wet-dry cycles and enhanced resistance to saline soil degradation.
Conclusions
- Natural fibers are effective and sustainable materials for stabilizing sulfuric saline soils.
- Fiber-reinforced soil exhibits improved mechanical properties, durability, and resistance to degradation.
- This approach offers an environmentally friendly solution for soil stabilization in arid regions.

The fineness modulus (FM) of aggregate is a numerical index that measures the coarseness or fineness of the particles. It is calculated by adding the cumulative percentages of aggregate retained on each of a specified series of sieves and dividing the sum by 100.
Consider performing sieve analysis on sand through a set of ASTM sieves. The weight of aggregate retained in each sieve and pan placed at the bottom is recorded, as given in Column B of Table 1.
To determine the fineness modulus of...
Salt stress—which can be triggered by high salt concentrations in a plant’s environment—can significantly affect plant growth and crop production by influencing photosynthesis and the absorption of water and nutrients.
Plant cell cytoplasm has a high solute concentration, which causes water to flow from the soil into the plant due to osmosis. However, excess salt in the surrounding soil increases the soil solute concentration, reducing the plant’s ability to take up...
Fiber-reinforced concrete significantly enhances the structural and nonstructural properties of traditional concrete by incorporating fibers like steel, glass, and polymers. These fibers, varying from natural ones such as sisal and cellulose to manufactured ones like polypropylene and Kevlar, are mixed into hydraulic cement with aggregates. Steel fibers, often preferred for their robustness, contribute to improved ductility, toughness, and post-cracking performance. The concrete is classified...
