Due to their sustainability as well as physical and mechanical performance, different natural fibers, both vegetal and animal fibers, have been successfully used in adobe mixtures (AMs) to enhance properties such as cracking control, flexural toughness and water erosion resistance, among others. However, the use of jute fibers (JFs), one of the most largely produced vegetal fiber worldwide, has not been extensively studied on AMs. Consequently, this study evaluates the effects of the incorporation of varying dosages (0.5 and 2.0 wt%) and lengths (7, 15, and 30 mm) of JFs on the physical/thermal/mechanical/fracture and durability performance of AMs, a specific type of earth-based construction material widely used globally. Experimental results showed that the incorporation of 2.0 wt% dosages of JFs increased the capillary water absorption of AMs, which might affect AM durability. The latter result could be explained by the additional porosity generated by the spaces left between the JFs and the matrix of adobe, as well as the inherent water absorption of the JFs. The incorporation of JFs significantly improved the behavior of AMs in terms of thermal conductivity, drying shrinkage cracking control, flexural toughness and water erosion performance, without affecting their compressive and flexural strength. For example, flexural toughness indices were increased by 297% and crack density ratio as well as water erosion depth values were reduced by 93% and 62%, respectively, when 2.0 wt%-15 mm length JFs were incorporated into AM. Since the latter combination of JF dosage and length provided the overall best results among AMs, it is recommended by this study as JF-reinforcement scheme for AMs for construction applications such as adobe masonry and earth plasters.

由于它们的可持续性以及物理和机械性能，植物纤维和动物纤维等不同的天然纤维已成功地用于土坯混合物（AMs）中，以增强诸如抗裂性，抗弯韧性和耐水侵蚀性等性能。但是，黄麻纤维（JFs）是世界上生产量最大的植物纤维之一，其使用方面尚未得到广泛的研究。因此，这项研究评估了掺入不同剂量（0.5和2.0 wt％）和长度（7、15和30 mm）的JF对AM的物理/热/机械/断裂和耐久性能的影响，具体而言全球广泛使用的地基建筑材料类型。实验结果表明，加入2.0 wt％剂量的JFs可以增加AMs的毛细吸水率，这可能会影响AM耐久性。后一种结果可以用JF和Adobe基质之间残留的空隙产生的额外孔隙率以及JF的固有吸水率来解释。JF的加入显着改善了AM的导热性，干燥收缩开裂控制，弯曲韧性和水蚀性能，而不会影响其抗压强度和抗弯强度。例如，当将2.0 wt％-15 mm长的JFs掺入AM中时，弯曲韧性指数分别提高了297％，裂纹密度比和水蚀深度值分别降低了93％和62％。由于JF剂量和长度的后一种组合在AM中提供了总体最佳结果，
