Abstract
The polythene bags have become an important part of human beings all over the world. Due to
such heavy usage, it has become an environmental problem to dispose these polythene bags thus
creating pollution in the environment in recent years. Since, these bags are not biodegradable, it
has to be utilized in construction industry so as to reduce its effect on environment.
This study examines mechanical and durability properties of concrete using polythene waste as a
partial replacement of fine aggregate at replacement levels of 0%, 5%, 10%, 15% and 20% by
weight of the fine aggregate.
Total 110 concrete specimens were cast in this study. The specimens were prepared for the
concrete mix of M30 grade and 0.45 water to cement ratio was maintained. The effects on different
properties of concrete with polythene waste were evaluated in this study. The specimens of
concrete mixes were tested for workability, compressive strength, split tensile strength, flexural
strength, carbonation depth, freeze-thaw resistance and load deflection behavior.
Test results of the samples shows that the workability, compressive strength, split tensile strength,
and flexural strength of concrete decreased with increase in plastic content. The carbonation depth
of concrete samples increased with increase in plastic content. When these concrete samples were
tested for freeze-thaw resistance the compressive strength, mass and dynamic modulus of samples
decreased after the freeze-thaw cycles. But the rate of reduction was low for 5% and 10%
replacement levels for all three parameters as compared to control mix. Load deflection behavior
showed ductile failure for the specimen having plastic waste. Energy absorption capacity and
flexural toughness factor showed increase in toughness with increasing amount of plastic waste
concentration.
