Effectiveness of Recycled Nylon Fibers in Mortar Comparing with Recycled PET and PVA Fibers

In this study, the authors focused on the potential and efficiency of recycled nylon fibers obtained from waste fishing nets as tensile reinforcement of mortar, and discussed comparisons with the experimental results of recycled PET and PVA fibers. The recycled nylon fibers were obtained through manual cutting of waste fishing net at different lengths of 20 mm, 30 mm and 40 mm, and mixed in mortar with the volumes of 1.0%, 1.5% and 2.0%. It was observed that recycled nylon fibers significantly enhances the mechanical properties of mortar as well as post peak response and ductile behavior. The addition of recycled-nylon fibers improved modulus of rupture up to 41% more than recycled-PET and PVA fibers. However, compressive strength decreased as fiber fraction and aspect ratio increased. Additionally, the use of Rnylon fibers is beneficial in terms of environmental effect and economic products.
