Concrete is poor in tension and it is usually reinforced with reinforcing bars within tensile zone to prevent collapse and cracking. These reinforcing steels are very expensive and are susceptible to corrosion when exposed to adverse environment. Hence, effort to reduce dependency on steel reinforcing bars in concrete is a welcoming development. In this study, jute yarn, that is an agricultural by-product and abundantly available is investigated in order to determine its impact on the mechanical strength characteristics of concrete. Compressive, split tensile and flexural strength of concrete were investigated at 0.1, 0.25 and 0.50% percentage content of jute yawn addition at varying lengths of 12, 14 and 16 mm. The optimum compressive strength was attained at 0.1% jute yawn of 14 mm length, while the optimum split tensile and flexural strength were obtained at 12 mm jute length and at 0.1% content. The optimum strengths for compressive, split tensile and flexural are 35.49, 3.14 and 4.06 N/〖mm〗^2, respectively.
