PROBLEM STATEMENT

• The waste is not bio-degradable, as in the case of plastics, and the nature cannot absorb it.

• Plastics take about 450 years to break down.• Most of this waste was buried in municipal

land without any used and burned in landfills.• Open dumping sites : required high

maintenance costs apart from causing the value of the surrounding real estate.

OBJECTIVE

To investigate the effect of plastic waste towards mechanical properties of polymer concrete

To investigate the effect of plastic waste towards durability of polymer concrete

To determine the optimum mix of plastic waste to be use in polymer concrete.

SCOPE

• Polypropylene (PP)• High Density

Polyethylene (HDPE) • Polyethylene (PET)

Type of plastic used

• Compressive strength• Flexural Strength• Water absorptionTesting

CONCLUSIONS

• Regarding to result, 3 types of recycled plastic are suitable for use in construction materials.

• The potential production of these components and their cost is conditioned absolutely by the possibility of obtaining the main raw material.

• they reduce plastic waste that causes pollution, instead of using up natural resources.

RECOMMENDATION

• It can be mix as a aggregate in a concrete.

• Size of plastic waste should be graded.• Add another durability to support a

data.
