High tensile strength is one of the most important mechanical properties desired in many materials used in civil engineering applications. Fibers are widely used in many materials that serve the purposes such as concrete and soil reinforcement, supporting structural elements, providing insulation, etc. Fibers produced from synthetic polymers are generally used to produce such materials. It can be stated that synthetic polymers can be produced very cheaply and quickly throughout the world, so they are easily accessible. Although this situation increases the demand for these materials day by day, synthetic polymers are generally non-biodegradable and cause significant damage to nature. This study investigated the effect of alkali treatment and bitumen coating on the tensile strength of hemp fiber, which is one of the natural fibers that can be used as an alternative to synthetic fibers. Therefore, hemp fibers were subjected to alkali treatment by soaking in a 5% sodium hydroxide (NaOH) solution. Unprocessed and alkali treated hemp fibers were then coated with bitumen. Tensile tests were carried out for each combination of unprocessed, alkali treated and bitumen coated fibers, and the effect of both alkali treatment and bitumen separately and together on the tensile strength was quantitatively presented.
