3. INTRODUCTION
 The concrete is the widely used construction
material across the globe due to its
adaptability,durability,strength,availability and
economy.
 River sand is the main raw material to prepare
concrete. But for an individual who wish to
construct a building, the biggest worry is the
availability of river sand.
 In recent years, the availability of river sand is
decreased drastically, because of illegal sand

 So there is a need of an alternative material to replace some
percentage of sand.
 To solve the above mentioned problem, we are experimenting on
polyethylene plastic waste which may be used as an alternative to
replace some percentage of sand.
 The purpose of this project is to study the mechanical properties of
concrete upon mixing with polyethylene plastic waste.

6. A Bhogayata-2017
Paper: Performance of concrete by using non recyclable plastic waste as concrete constituent
They have studied the environment friendly disposal of shredded plastic bags in
concrete mix to be use in construction industry which have dire need for alternative material to be
use in lieu of conventional materials. Different test results were analyzed after testing on 48 x
concrete cubes(150mm x 150mm x150mm) prepared from varying percentage of polyethylene
fibers (0.3, 0.6, and 0.9 to 1.2% of volume of concrete) with conventional concrete material to
prepare mixes. Two type of plastic bag fibers were used, one cut manually (60mm x 3mm) and
another shredded into a very fine random palettes. Cubes were tested for 7&28 days compressive
strength and compaction. They concluded that good workability was shown by the mix added
with shredded fibers due to its uniform and higher aspect ratio evenly sprayed in the mix.
Addition of plastics up to 0.6% is considered suitable after which reduction in compressive
strength and compaction is seen affected. They observed that strength loss was less in concrete
having shredded fibers of plastic as compare to hand cut macro fibers. Their research focus was
only on comparative study of compressive strength but no work was carries out on other concrete
properties like tensile strength, modulus of elasticity and density of concrete.

Paper: Study of strength property of concrete using waste plastic and steel fibers.
This study presents the results of addition of waste plastics along with steel fibers with
an objective to seek maximum use of waste plastic in concrete. Two different categories of mix
were casted in cubes (150mm x 150mm x 150mm), one with varying percentages of plastic
wastes (0.2%, 0.4%, 0.6%, 0.8% and 1% weight of cement) and another mix of plastics
waste/steel fibers (0.2/0.1, 0.4/0.2, 0.6/0.3, 0.8/0.4 and 1/0.5 % by weight of cement) to study the
compressive strength at 7 and 28 days strength. The combine mix of plastic waste and steel fibers
has shown more strength as compare to concrete mix prep only with plastic waste. He has
reached to conclusion that a plastic waste of 0.6% weight of cement when used with steel fiber of
0.3 % (weight of cement) has shown the maximum compressive strength. This study has really
focused on addressing the issue of reduced compressive strength with addition of plastic waste.
Steel fibers when used along with plastic wastes will affect all the properties of concrete but the
researcher only focused on compressive strength property which is insufficient to give clear
picture of concrete behaviour.

8. OBJECTIVES
 To prepare concrete by replacing some percentage of sand with
Polyethylene plastic waste.
 To prepare a light weight concrete.
 To reduce the pollution level in environment which is caused by
plastic waste.
 To prepare concrete mix economically.

9. MATERIALS
1.Cement: It is the main raw material to manufacture the concrete. Portland pozzolana cement is
considered. Portland Pozzolana Cement is a kind of Blended Cement which is produced by either
intergrinding of OPC clinker along with gypsum and pozzolanic materials in certain proportions or
grinding the OPC clinker, gypsum and Pozzolanic materials separately and thoroughly blending
them in certain proportions.

10. 2.Fine Aggregate: Either river sand or manufactured sand can be used as
fine aggregate
RIVER SAND M-SAND
3.Coarse Aggregate: The coarse aggregate that is of size not more than
20mm are used to manufacture the concrete.
COARSE AGGREGATE

11. 4.Polyethylene Plastic: Polyethylene plastic is widely used for manufacturing
various containers, dispensing bottles, wash bottles, tubing, plastic parts for
computer components, and various molded laboratory equipment. Its most
common use is in plastic bags.

12. METHODOLOGY
The preparation of this concrete involves the following processes
 Batching of materials
 Mixing of materials
 Preparation of cubes
 Curing of cubes
1.Batching of materials: Batching is the process in which the quantity or proportion of materials
like cement, aggregates, water, etc. are measured on the basis of either weigh or volume to
prepare the concrete mix. Proper Batching improves the workability of concrete by reducing the
segregation or bleeding in concrete.Cement sand and coarse aggregate can be measured on the
basis of mix design. This project aims to replace some percent of sand with plastic waste. So the
plastic waste selected for the manufacturing process should have the size, same or some what
equal to the fine aggregate. This can be achieved by shredding of plastic using the plastic
shredding machine.

13. A plastic shredder is a machine used to cut plastic into smaller pieces. In the
process, the plastic is fed into the machine and the slowly rotating blades cut the
plastic waste into smaller pieces.

2.Mixing of materials: The mixing of selected materials to get a good concrete
mixture is known as mixing.
Types of mixing are
Hand mixing
Machine mixing

14. 3.Preparation of cubes: After proper mixing of materials the concrete
should be poured into respective cubes which have different size.
4. Curing of cubes : The prepared cubes should be cured to 7 days and
28 days respectively before the commencement of test on that cubes.
