Abstract:
Given the growing demand for sustainable alternatives in pavement and geotechnical engineering, the use of agricultural residues as soil reinforcement materials has gained attention as a technically and environmentally viable approach. Among these residues, banana fiber stands out for its low cost, renewable nature, and wide availability in tropical regions. This study presents a preliminary investigation of the interaction between banana fiber and sandy soil through morphological and microanalytical characterization. The experimental procedure involved adapting the compacted soil molding process (MCT method) to prepare small-scale fiber–soil specimens under conditions representative of field compaction. After seven days of air curing, the fibers were carefully removed and analyzed using scanning electron microscopy (SEM) coupled with energy-dispersive X-ray spectroscopy (EDS) to observe the interface and identify possible physicochemical interactions. The results revealed similar surface compositions between the fiber portions embedded in and exposed from the soil, suggesting the occurrence of capillary sorption and moisture-induced ionic migration along the fiber structure. These findings indicate that banana fiber exhibits potential compatibility with sandy soils, supporting its future application as a sustainable reinforcement material. This methodological adaptation establishes the foundation for subsequent mechanical evaluations, such as pull-out and triaxial tests, aimed at quantifying the interfacial strength and overall contribution of natural fibers to soil improvement.
