Mechanical Properties of Mortar Reinforced with Recycled Nylon Fiber from Waste Fishing Nets

Derelict fishing nets are becoming an environmental issue. Since those fishing nets are threatening many marine creatures, it is necessary to find suitable recycling solutions. In this study, recycled nylon fiber from waste fishing nets was used as a reinforcing material in mortar. Parameters which are likely to have effect on the changes in mechanical property of the mortar such as geometry of fiber and percent fiber content by volume were examined. Furthermore, compressive strength, flexural capacity, flowability of fresh mortar, and failure behavior were extensively investigated to evaluate the effectiveness of the reinforcement. Experimental results showed higher flexural capacity of the mortar reinforced with recycled nylon fiber. In addition, post-peak behavior and flexural capacity after the peak load were investigated. Adding fibers also shows improvement in ductility of the beams and postpones beam failure.
