Experimental investigation and PGCN-based prediction of the mechanical properties of recycled nylon fiber reinforced concrete using waste fishing nets
AI summary Read the abstract
Researchers tested concrete mixed with recycled nylon fibers from old fishing nets, finding that adding 3% fibers increased tensile, compressive, and flexural strength compared to regular concrete. A computer model was also used to predict the concrete's strength, suggesting waste fishing nets could be reused in construction materials.
Marine plastic pollution has grown to be an alarming problem in recent years, and abandoned nylon fishing nets are a key contributing factor. In order to improve concrete's mechanical qualities and sustainability, this study looks into recycling waste fibers. This study suggests conducting an experiment to examine the durability and mechanical characteristics of concrete reinforced with recycled nylon fibers. This work's main goal is to evaluate the efficacy of recycled nylon fibers derived from waste fishing nets in improving the mechanical characteristics and longevity of masonry. Initially, the input data is collected from Concrete Compressive Strength dataset. A Progressive Graph Convolutional Network is used to forecast Concrete reinforced with recycled nylon fiber: its mechanical characteristics (RNRC) (PGCN). Concrete mixtures with zero, one, two, and three percent recycled nylon fibers were tested mechanically using standard testing methods. Compressive, tensile, and flexural strength measures were part of these testing. Compared with conventional concrete, the RNRC containing 3% recycled nylon fibers achieved significant improvements in mechanical performance, Tensile strength increased from 2.67 MPa to 3.45 MPa (29.21%), and compressive strength increased from 23.37 MPa to 28.07 MPa (20.11%) and flexural strength increasing from 3.27 MPa to 8.10 MPa (147.71%) after 28 days of curing. By contrasting RNRC with regular concrete, the study demonstrates how recycled fibers can enhance concrete performance while fostering environmental sustainability. The proposed method is implemented in MATLAB. The study provides a comparison between RNRC with standard concrete, demonstrating that recycled nylon fibers can enhance concrete performance while promoting environmental sustainability.

Researchers incorporated recycled Nylon-6 fibers from discarded fishing nets into M40 grade concrete and found that moderate fiber dosages improved crack resistance, enhanced post-cracking ductility, and met structural strength requirements, demonstrating a dual benefit of diverting marine plastic waste while improving concrete performance.
Effect of recycled waste nylon granules and treated sisal fiber on the physical, mechanical, and durability properties of sustainable concrete
AI summary Read the abstract
Researchers found that mixing recycled nylon waste (like old fishing nets or fabric) with treated sisal plant fibers into concrete actually made it stronger, more crack-resistant, and better at resisting heat damage—not weaker, as you might expect. This matters because it offers a practical way to keep plastic waste out of landfills and oceans (where it can break down into microplastics that affect ecosystems and human health) while building more durable, longer-lasting construction materials.
The effect of compacted nylon particles and silica fume on mechanical properties and water absorption of lightweight concrete: experimental and theoretical study
AI summary Read the abstract
Researchers tested lightweight concrete made with recycled compacted nylon particles replacing some sand, plus added silica fume. Adding nylon generally weakened the concrete's strength but reduced water absorption, while silica fume helped offset some strength loss and further reduced water absorption. The team also built mathematical models to predict these properties.
