天然安定材（タンニン、石膏、火山灰）とフィケ繊維を用いた土系複合材料の力学特性を実験的に評価。フィケ繊維添加により延性が向上し、火山灰とフィケ繊維の組み合わせで圧縮強度2.85 MPa（基準比38%増）を達成。曲げ強度は0.65 MPaと基準の2倍を示し、低炭素建築材料としての可能性を確認。
English
This paper experimentally evaluates earth composites reinforced with natural stabilizers (tannins, gypsum, volcanic ash) and fique fibers. Results show fique fibers improve ductility, and volcanic ash with fique achieves 2.85 MPa compressive strength (38% increase). Flexural strength reaches 0.65 MPa, double the reference, demonstrating potential for low-carbon construction.

📄 Abstract（原文）
Vernacular architecture has provided valuable insights into how the building design of the future should be conceived, in an era that demands a balanced relationship between human activity and the environment. Earth, a material historically used worldwide for its accessibility, low cost, and versatility, stands out as a key component in this transition. The aim of this work is to experimentally demonstrate the potential of biodegradable earthen composites reinforced with natural stabilisers and fique fibres, as a sustainable alternative to conventional cement-based materials. A series of five mixtures were tested, combining an earth matrix (sand + clay) with stabilisers (tannins, gypsum, and volcanic ash) and natural fibres of fique (Furcraea andina). The mechanical characterisation included unconfined compressive strength (UCS) and flexural strength tests on prismatic specimens (160 × 40 × 40 mm). Results show that the addition of fibres significantly improved ductility, while the inclusion of stabilisers enhanced compressive behaviour. The highest UCS value (2.85 MPa) was obtained in samples stabilised with volcanic ash and fique, representing an increase of 38 % compared to unstabilized earth composites. The flexural strength reached 0.65 MPa, doubling the value of the reference mixture without additives. These results confirm that natural tannin-based and pozzolanic stabilisers can effectively replace cement in earthen materials while maintaining biodegradability and low embodied energy. The proposed composite demonstrates high mechanical stability, low environmental impact, and complete reintegration into natural cycles, offering a feasible model for low-carbon construction and material circularity in future urban development.
