Abstract
Bakelite, a synthetic thermosetting polymer, has been extensively utilized in the production of various
components across different industries in India. As the demand for Bakelite continues to rise, so does
the challenge of managing its waste, which poses significant environmental concerns due to its non
biodegradable nature. In this context, utilizing Bakelite waste as a partial substitute for coarse
aggregate in concrete presents an innovative and environmentally sustainable approach to waste
management. This method not only helps to alleviate the problems associated with the disposal of
Bakelite but also contributes to the broader objective of reducing plastic waste in landfills. Research
studies indicate that increasing the percentage of Bakelite incorporated into concrete mixes results in
a notable decrease in both the compressive strength and density of concrete blocks, alongside a
reduction in their thermal conductivity. These changes in mechanical properties raise important
questions about the viability of using Bakelite waste in construction applications. Moreover, the
challenges associated with Bakelite disposal, including stringent regulations against landfilling and
open burning due to the harmful emissions released, have prompted researchers to explore
alternative avenues for repurposing waste Bakelite within the civil engineering sector. In this study,
we focus on a comprehensive examination of the mechanical properties of concrete that incorporates
Bakelite waste as a partial substitute for coarse aggregate. Through systematic testing and analysis,
we aim to determine the optimal percentage of Bakelite that can be used in concrete mixes while still
maintaining acceptable strength and durability characteristics. Our findings will contribute valuable
insights into the feasibility of using Bakelite waste in concrete production, ultimately supporting
sustainable construction practices and promoting environmental conservation efforts in the industry.
