This study examines the thermal insulation capacity, mechanical performance, and high-temperature resistance of geopolymer composites reinforced with 5%, 10%, and 20% hemp fiber. This research aims to develop sustainable, high-performance construction materials with enhanced thermal efficiency and structural integrity. Thermal conductivity, compressive strength, and flexural strength tests were conducted on geopolymer mortar specimens to evaluate their performance. The results indicate that increasing hemp fiber content improves thermal insulation, with the 20% hemp fiber mixture achieving the lowest thermal conductivity. However, hemp fiber reinforcement leads to reductions in both compressive and flexural strength while maintaining structural stability. These findings highlight the potential of hemp fiber-reinforced geopolymers as eco-friendly alternatives to conventional insulation materials, particularly for applications requiring fire resistance and thermal efficiency, despite the observed decrease in mechanical properties. This research contributes to the advancement of sustainable construction materials and underscores the viability of hemp fiber-reinforced geopolymer mortars for industrial applications. Further studies are recommended to optimize mix designs and assess long-term durability under various environmental conditions.
本研究考察了用5%、10%和20%的麻纤维增强的地质聚合物复合材料的保温能力、力学性能和耐高温性能。本研究旨在开发具有更高热效率和结构完整性的可持续高性能建筑材料。对地质聚合物砂浆试件进行了热导率、抗压强度和抗弯强度测试，以评估其性能。结果表明，增加麻纤维含量可提高保温性能，含20%麻纤维的混合物热导率最低。然而，麻纤维增强导致抗压强度和抗弯强度降低，同时保持结构稳定性。这些发现突出了麻纤维增强地质聚合物作为传统保温材料的环保替代品的潜力，特别是对于需要耐火性和热效率的应用，尽管观察到力学性能有所下降。本研究有助于可持续建筑材料的发展，并强调了麻纤维增强地质聚合物砂浆在工业应用中的可行性。建议进一步研究以优化配合比设计，并评估在各种环境条件下的长期耐久性。
