In this study, we estimate the potential efficiency of waste fishing net (WFN) fibers as concrete reinforcements. Three WFN fiber concentrations (1, 2, and 3% by volume) were mixed with concrete. Compressive strength, toughness, splitting tensile strength, and biaxial flexural tests were conducted. Compressive strength decreased but other properties increased as a function of fiber proportions. According to the mechanical strength observations and the ductility number, WFN fibers yielded benefits in crack arresting that improved the postcracking behavior and transformed concrete from a brittle into a quasi-brittle material. It is inferred that WFN fiber is a recycled and eco-friendly material that can be utilized as potential concrete reinforcement.
在本研究中，我们评估了废弃渔网（WFN）纤维作为混凝土增强材料的潜在效率。将三种WFN纤维浓度（按体积计分别为1%、2%和3%）与混凝土混合。进行了抗压强度、韧性、劈裂抗拉强度和双轴弯曲试验。抗压强度随纤维比例的增加而降低，但其他性能有所提高。根据力学强度观测结果和延性数值，WFN纤维在阻止裂缝方面具有优势，改善了开裂后的性能，并使混凝土从脆性材料转变为准脆性材料。据推断，WFN纤维是一种可回收的环保材料，可作为潜在的混凝土增强材料。
