A relatively better performance of jute fiber and yarn reinforced concrete composites can open up a wide access to application of natural resources in concrete strengthening. In order to achieve this goal, an experimental investigation on the flexural, compressive and tensile strengths of Jute Fiber Reinforced Concrete Composites (JFRCC) and Jute Yarn Reinforced Concrete Composites (JYRCC) has been conducted. To draw a specific conclusion, the mix ratios of 1:1.5:3 and 1:2:4 (by volume) of concrete have been maintained with incorporation of jute fiber and yarn in concrete mortar having different cut lengths with distinct volumetric ratios. Finally, a comparison of the JFRCC and JYRCC strength increments with respect to the plain concrete has been investigated. A significant increment of compressive, flexural and tensile strength was observed only for a short cut length having a low volumetric ratio, where JYRCC increment value was always found progressive. A far more regular arrangement and adequate mixture of JYRCC was also visualized compare to JFRCC in concrete mortar. All the principal increment values were found only in case of JYRCC with a mix ratio of 1:1.5:3. So, it can be concluded that the presence of jute yarn and more cement content can strengthen the concrete to a great extent.

黄麻纤维和纱线增强的混凝土复合材料的相对较好的性能可以为在混凝土增强中使用自然资源提供广泛的机会。为了实现这一目标，对黄麻纤维增强混凝土复合材料（JFRCC）和黄麻纱线增强混凝土复合材料（JYRCC）的抗弯，抗压和抗张强度进行了实验研究。为了得出一个具体的结论，通过将黄麻纤维和纱线掺入具有不同切割长度和不同体积比的混凝土砂浆中，可以保持混凝土的混合比为1：1.5：3和1：2：4（按体积计）。最后，对普通混凝土的JFRCC和JYRCC强度增量进行了比较。压缩的显着增加 仅在具有低体积比的短切长度上观察到弯曲和拉伸强度，其中总是发现JYRCC增量值是渐进的。与JFRCC在混凝土砂浆中相比，还可以看到JYRCC更加规则的布置和充分的混合。仅在JYRCC混合比为1：1.5：3的情况下，才能找到所有主要增量值。因此，可以得出结论，黄麻纱的存在和更多水泥含量可以在很大程度上增强混凝土的强度。
