Bricks have been a predominant building material throughout history, known for their exceptional strength and resilience. With the increasing emphasis on sustainable and locally sourced construction materials, this study explores the incorporation of waste apparel materials into conventional brick manufacturing processes. The waste apparel materials investigated in this research include polyester, polyester cotton (PC), and polyester viscose (PV). The manufacturing process involved subjecting a clay mixture to various treatments, with modifications based on the material type, manufacturing technique, and desired characteristics of the final product. Different weight measurements of waste apparel were added to the bricks to assess their impact on physical properties. This study focused on the physical characteristics of the resulting bricks, with a particular emphasis on compressive strength and water absorption. The experimental results revealed that the addition of 25 g of PC, PV, or polyester to a brick resulted in a remarkable 45 percent increase in compressive strength while simultaneously reducing water absorption. However, the investigation also demonstrated that exceeding a certain amount of textile waste in the brick composition can lead to a decline in compressive strength compared to the original results. Thus, a careful balance must be struck when incorporating waste apparel to achieve optimal improvements in brick performance. These findings open up possibilities for utilizing discarded clothing as a reinforcement in conventional brick production, highlighting its potential as a viable and environmentally friendly solution. By diverting waste apparel from landfills and utilizing it in construction materials, this approach offers a sustainable method for enhancing the properties of bricks while reducing environmental impacts. In conclusion, this study provides valuable insights into the incorporation of waste apparel into conventional brick manufacturing, presenting a novel avenue for enhancing brick performance and promoting a more eco-conscious approach to construction practices. Further research and development in this area can pave the way for more widespread adoption of sustainable and locally sourced building materials. © 2024 Elsevier B.V., All rights reserved.
