Abstract
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.

The civil construction industry has contributed significantly to development worldwide
The influences of the waste fishing net (WFN) fibers on the 28-day compressive behavior are shown in samples and plain concrete at 28 days are listed in Table 6 (refer to Equation (1))
The plain concrete samples were broken according to a brittle scenario at the peak load, while other WFN fiber-reinforced concrete samples were broken but contained cracks around their cylindrical surfaces
Summary
The civil construction industry has contributed significantly to development worldwide. The consumption of mineral resources and fossil fuels in conjunction with the huge amounts of waste generated has affected the environment. According to [1], in 2019, CO2 emissions and energy consumptions caused by the construction sector were recorded at 38 and 35%, respectively, as compared with the proportions pertaining to the entire industry. The environment is worsening owing to an increase in marine litter. According to [2], the growth of annual marine plastic litter is predicted to increase from 11 million metric tons in 2016 to 29 million metric tons in 2040. Almost all marine litter is made from poor or non-degradable materials; it is harmful to the ecosystem. WFNs are generally made from nonbiodegradable materials that are advantageous in fisheries
