| dc.description.abstract | Plastic waste is a significant environmental
concern due to its negative impact on the ecosystem. This
study investigated the use of waste plastic as a partial
replacement for sand in M15 grade concrete and assessed
its effects on the physical and mechanical properties of
concrete. Ten concrete mixtures were prepared with
varying levels of plastic substitution: 0%, 2%, 4%, 6%,
8%, 10%, 12%, 14%, 16%, and 18%. Concrete cubes
measuring 150 x 150 x 150 mm were cast for each mixture
to evaluate workability, unit weight, compressive strength,
and tensile strength. Slump tests were performed on-site
to assess workability. Two cubes from each mixture were
cured in water and tested for compressive strength at 7 and
28 days. Results indicated that plastic replacement of up to
10% improved mechanical and physical properties
compared to conventional M15 concrete. This study
highlights the potential benefits of incorporating waste
plastic into concrete, including enhanced material
properties, cost savings, and environmental benefits.
Reusing waste plastic in concrete not only mitigates
environmental issues related to plastic waste but also
contributes to more sustainable and economical
construction practices. | en_US |
