| description | Polypropylene, steel, and carbon fibers are used to increase the ductility and toughness of concrete materials. In recent years, studies on the use of natural fibers have increasingly continued. Among natural fibers, hemp fiber has the highest tensile strength value. The aim of this study was to discuss and present the results of the experimental study on the use of cement-based hemp shives and fibers to increase the ductility of mortars. Another aim is to increase the use of hemp in the construction field by using more economical and natural fibers. Various binders and different amounts of fibers and shives were added and their effects on flexural strength were investigated. Water absorption and flexural tests and scanning electron microscope and X-ray diffraction analysis were performed on the produced samples. Particle and hole size distributions and stereo microscope images of the samples are given. The use of hemp fibers was observed to improve flexural strength, while shives were not significantly improved flexural strength. |
