Abstract: The tensile properties of mortal reinforced with polyvinyl alcohol (PVA) fibers were studied in this article. Specimens reinforced with varying volume fractions of different-sized fibers were tested in direct tension. Pull-out tests were also conducted to evaluate the interfacial properties between the PVA fiber and mortar matrix. In addition, scanning electron microscopy was used to study the failure mechanism of the fibers in the direct tension test specimens. To study fiber distribution, images of the specimen cross-sections obtained with an optical microscope were analyzed. It was found that if the influence of fiber length is taken into account, the first peak stress can be expressed as a unique function of the measured fiber distance, regardless of fiber volume fraction and diameter.
