Abstract

This research study investigates the innovative use of Bakelite waste as a partial substitute for coarse aggregate in concrete, focusing on its effects on various mechanical properties and overall performance of the concrete mix. With the growing concern over waste management and environmental sustainability, the incorporation of non-biodegradable materials, such as Bakelite, into construction practices offers a dual benefit: reducing the volume of waste destined for landfills while simultaneously addressing the increasing demand for natural aggregates in concrete production. In this study, concrete samples were prepared with varying levels of Bakelite waste replacement (0%, 10%, 20%, and 30%) and subjected to rigorous mechanical testing at 7, 14, and 28 days to assess their compressive strength, density, water absorption, and durability. The results demonstrated that the inclusion of Bakelite waste influenced the mechanical performance of the concrete, with noteworthy improvements observed at lower replacement levels, specifically 10% and 20%. These levels not only maintained structural integrity but also enhanced certain performance characteristics, such as workability and resistance to water absorption, when compared to traditional concrete. The findings of this research contribute significantly to the field of sustainable construction by demonstrating that Bakelite waste can be effectively utilized in concrete applications, thus providing an environmentally friendly alternative to conventional materials. Additionally, this study highlights the potential for Bakelite-modified concrete to serve in non-structural applications where weight reduction is critical, offering insights into the practical applications of waste materials in construction. This work serves as a foundational study for further exploration into the long-term performance and durability of concrete incorporating Bakelite waste, ultimately aiming to advance the use of recycled materials in the construction industry and promote sustainable building practices.
