“…Therefore, the effects of fibers on the R c of concrete need to be thoroughly clarified. On the other hand, almost all previous studies have reported an increase in R f [5,12,22,24,26] and R it [23,25] with the inclusion of fibers. But the proportion of fiber plays a crucial role here; up to a certain proportion of fiber, R f and R it increase, and with a further increase in fiber dosage, there is a decrease in strength due to its balling problem and uneven distribution [5].…”

The valorization of waste fishing trawl (WFT) and waste fishing rope (WFR) fibers in cementitious materials (CMs) has gained attention in recent years; however, the lack of information on the cutting and cleaning techniques for these fibers hinders their widespread commercial utilization. Existing research primarily relies on manual cutting, which proves to be impractical for large-scale production due to its time-consuming nature and lack of industrial feasibility. This research is a component of the VALNET project and introduces an innovative technique that utilizes the cutting mill to convert WFT and WFR into fibers to effectively overcome the constraints of earlier methodologies. By employing a rotor with blades, this apparatus enables efficient and precise cutting of WFT and WFR, eliminating the need for labor-intensive manual cutting. The sustainable cleaning of WFT and WFR was carried out utilizing rain and wind by placing them outside for a certain period of time. The advancements presented in this study provide a pathway for an efficient and scalable valorization of WFT and WFR fibers in CM. The study focused on analyzing the impact of varying fiber sizes and percentages on the mechanical properties of CM. Different sizes obtained from the cutting machine and different fiber percentages were examined to gain a better understanding of their influence. The fibers obtained by the utilization of a 20 mm sieve yield optimal outcomes, while the incorporation of fibers at a volume fraction of 0.5% yields the most favorable results. Furthermore, the study presents evidence of a noticeable rise in porosity resulting from the incorporation of WFT and WFR fibers, regardless of their size and proportion. Porosity slightly increases as the fiber length increases, but the rise in fiber proportion leads to a significantly greater increase in porosity.

Research on the use of recycled plastics in construction materials has increased over the last decade. The major trends and recycling applications for plastic waste in construction materials are reviewed in this chapter with a special focus on the use of discarded fishing nets as reinforcing material. The experimental part of this project included the characterization of discarded fishing nets of polyethylene with the aim of discovering new recycling alternatives for the use of fishing nets as reinforcement in different types of construction materials. The fishing net material was added either in the form of fibers or as pieces of net. The characterization of the polyethylene fibers showed that the material properties were in the same range as some commercially available fibers used in construction materials. The influence of the addition of fishing nets to construction materials was evaluated based on the mechanical performance and early-age shrinkage properties of cement-based mortars, gypsum, and earth-based adobe bricks. The results showed that the addition of fishing net fibers improved the post-crack performance of all types of tested construction materials, but the most prominent gain in mechanical properties was obtained for the earth-based adobe bricks. The addition of fibers was also found to mitigate shrinkage deformations and cracking of cement-based and earth-based materials.
