Performance of Concrete Using Light Waste PET Fibre

Abstract

The volume of polymeric wastes like polyethylene terephthalate bottles (PET) is increasing at a fast rate. PET bottles annual consumption represents more than 300,000 million units. The majority of the PET waste is sent to landfill. Since PET waste is not biodegradable, it can remain in nature for hundreds of years. Previous investigations already confirmed the potential of PET waste in replacing aggregates in concrete and represents better option than send it to landfill. This paper reviews researches published on the performance of concrete containing PET wastes. In this researches PET waste will be incorporated with an established binder namely fly Ash. The increase of workability is caused by the small spherical shapes of the fly ash that reduces the friction between cement and aggregates. Then it will results in an increase in the workability and flow of fresh concrete. Overall, the decision of using recycled waste plastic as fiber in structure for the design of structures provides enough benefits that will make it worthwhile to be considered as an economical attractive option. Once the use of performance concrete using light fibre becomes more popular and the importance of research contribution in providing technical knowledge on this new material becomes apparent. Furthermore this paper will bring new name for the new combination waste material is called Performance of Waste Light PET Fibre Concrete (WLPFC).
