ABSTRACT : Plastics plays an important part in our modern lifestyle, and the global plastic production has increased immensely which contributed greatly to the production of plastic-related waste.This paper summarizes the benefits of using straight fibres from waste polyethylene Terephthalate (PET) bottles .The percentage of fibres added to M30 mix concrete were 0%, 0.6%, 0.8% , 1.0% & 1.2% for three aspect ratios 30,50 and 70.The strength parameters like Compressive, Split tensile ,Flexure tests and Impact tests are studied for 7 das & 28 days.The results of the tests are compared with conventional concrete without any fibre .
Concrete literally plays an vital role in infrastructure due to its workability,durability and strength. However concrete is weak in tension, brittlesnes ,resistance to cracking, impact strength and heavy weight.To improve these weakness of concrete different types of fibres are introduced in concrete and so formed concrete is termed as fibre reinforced concrete. Fiber reinforced concrete is concrete containing fibrous substance which increases its structural integrity.
Disposal of plastic waste has emerged as an important environmental challenge and its recycling is facing roadblocks due to its nondegradable nature. Bottles made of polyethylene terephthalate (PET) can be recycled to reduce the amount of waste going into landfills.PET bottles in fibre forms can be used to get mechanical properties of concrete.
The study was carried out by using PET fibers in aspect ratios 30 (60 mm X 2 mm), 50 (100 mm X 2 mm) and 70 (140 mm X 2 mm) and incorporating them as weight of cement at different intervals 0f 0.6%, 0.8%, 1.0% and 1.2%.
