USE OF POLYETHYLENE TEREPHTHALATE IN CONCRETE-A BRIEF REVIEW

Concrete, one of the major pollutants in the construction field to be made green is the need of the hour. Though concrete is largely used, its lifetime has become a huge concern due to the cracks produced in it as a result of shrinkage.The addition of fibers into the concrete has been found to improve several of its major properties like tensile strength, cracking resistance, impact, wear and tear, ductility etc as concrete is very much weak in tension which readily undergoes cracking.To resolve these problems and to make the concrete eco-friendly, waste plastic fibers can be employed in concrete in the name of Plastic Fiber Reinforced Concrete (PFRC). As far now, papers have been surveyed on concrete reinforced with plastic fibers such as polyethylene, polypropylene, polyvinylchloride, polyethylene terephthalate(PET). Regarding the domestic consumption of plastics these many years, PET stands first and therefore the use of concrete reinforced with recycled PET fibers as a construction material can be suggested. In future, we are going to propose and investigate the effect of the addition of various percentages of PET strips in the form of mesh in the plastic concrete
