| Abstract Scope |
The construction sector relies heavily on mineral raw materials and cement-based products, motivating the search for sustainable alternatives based on plant-derived residues. This study reviews the potential incorporation of natural fibrous wastes into construction materials, emphasizing their benefits, limitations, and technological potential. Scientific articles, review papers, and technical studies published between 2000 and 2025 were analyzed, focusing on sisal, coconut, jute, curaua, bamboo, piassava, and other lignocellulosic residues. The reviewed literature indicates that these fibers can improve crack control, toughness, reduce material density, and enhance thermal and acoustic performance when incorporated into cementitious composites. However, challenges such as high water absorption, natural variability, and degradation in alkaline environments still limit their long-term performance. The findings demonstrate that the successful application of natural fibrous wastes depends on appropriate fiber treatment, optimized incorporation levels, fiber-matrix compatibility, and adequate durability assessment under service conditions. |
