Abstract - The integration of industrial by-products into
polymer composites has become a vital area of research for developing eco-friendly materials with enhanced mechanical properties. Red mud, an industrial waste generated during the Bayer process of alumina production, presents an abundant and cost-effective filler material for polymer composites. This review paper explores the fabrication techniques and mechanical characterization of red mud-based polymer composites, with a focus on their mechanical performance, environmental impact, and industrial applications. The findings indicate that red mud, when used as a filler material, enhances the mechanical strength, thermal stability, and durability of polymer composites. However, the composites face challenges related to filler dispersion, interfacial bonding, and environmental compatibility. Figure 1: Sample of Red Mud

Here’s a sample table summarizing the mechanical characterization of red mud-based polymer composites. This table includes various mechanical properties such as tensile strength, flexural strength, impact strength, hardness, and wear resistance, along with typical findings and influences of red mud content.
1. INTRODUCTION The integration of waste materials into polymer composites has gained significant momentum due to increasing environmental concerns and the desire for sustainable material solutions. Red mud, a highly alkaline by-product of the Bayer process for alumina extraction from bauxite, poses significant environmental disposal issues due to its large quantities and hazardous nature. The global accumulation of red mud exceeds millions of tons annually, and its disposal remains a challenge, given the risk of soil and water contamination. One potential solution to red mud disposal is its use as a filler in polymer composites. By incorporating red mud into polymer matrices, researchers can create new composite materials that not only utilize this industrial waste but also improve the mechanical properties of polymers, making them suitable for various structural and functional applications. These composites can replace traditional, more expensive, and less sustainable fillers like glass fibers and carbon fibers. This review aims to explore the fabrication techniques and mechanical properties of red mud-based polymer composites and examine their potential for industrial applications.
