Concrete is strong in compression but weak in tension, brittleness and also having possibility of
cracks formation as soon as it is placed. These three drawbacks don’t permit the use normal
concrete in pavements as they results in lack of ductility along with fracture and failure. These
weaknesses in concrete can be mitigated by using fibers as reinforcement or aggregate
replacement in the concrete mix. Waste materials in the form of polyethylene and rubber tires,
which cause environmental pollution, can be recycled and used effectively in the concrete as
fine aggregate replacement. Polyethylene is a synthetic hydrocarbon polymer, which may
improve the ductility, strength, shrinkage characteristics etc up to a certain limit. This thesis
deals with the effect of addition of polymeric waste materials on the various properties of
concrete. Shredded polyethylene and crumb rubber tire passing through 4.75 mm size sieve will
be used as fine aggregate replacement in different percentages each by volume. Grade of
concrete proposed is M30. Different tests of materials, strength and durability tests on control
and modified concrete mix will perform in the laboratory for comparing and analyzing fresh,
hardened and durability properties of concrete. Practical values will be verified with the
theoretical values within the permissible limits.
