使用合成纤维和天然纤维生产混凝土的研究不断深入。大多数材料因其更高的柔韧性、耐用性和强度而变得流行。然而，目前的研究探讨了尼龙和黄麻纤维共同增强的水泥混凝土的工程性能。混凝土混合物中使用了不同比例和长度的尼龙和黄麻纤维。因此，研究了尼龙和黄麻纤维对混凝土和易性、密度、吸水率、压缩强度、拉伸强度、弯曲强度和干燥收缩的综合影响。结果表明，掺入体积分数为 1% 的尼龙和黄麻纤维的混凝土在 90 天时与对照混凝土相比，其抗压强度、劈裂拉伸强度和弯曲强度最大分别提高了 11.71%、14.10% 和 11.04%。然而，混凝土的吸水率随着尼龙和黄麻纤维含量的增加而增加。 90天后，尼龙和黄麻纤维一起添加，混凝土的干燥收缩减少。因此，本研究中讨论的尼龙和黄麻纤维的节约应用可用于混凝土生产。
The use of synthetic fiber and natural fiber for concrete production has been continuously investigated. Most of the materials have become popular for their higher flexibility, durability, and strength. However, the current study explores the engineering properties of cement concrete reinforced with nylon and jute fibers together. Varying proportions and lengths of nylon and jute fibers were utilized in the concrete mixture. Hence, the combined effects of nylon and jute fibers on workability, density, water absorption, compressive, tensile, flexural strength, and drying shrinkage of concrete were investigated. Results showed that concrete with 1% of nylon and jute fibers together by the volume fraction showed a maximum enhancement of the compressive strength, split tensile strength, and flexural strength by 11.71%, 14.10%, and 11.04%, respectively, compared to the control mix of concrete at 90 days. However, the water absorption of concrete increased with increasing nylon and jute fiber contents. The drying shrinkage of concrete decreased with the addition of nylon and jute fibers together after 90 days. Thus, the sparing application of both nylon and jute fiber as discussed in this study can be adopted for concrete production.
