The Mechanical Properties of PET Fiber Reinforced Concrete from Recycled Bottle Wastes

This research is carried out to investigate the performance of concrete containing Polyethylene Terephthalate (PET) bottle waste as fiber. PET bottle waste was chosen because it is being thrown after single use and cause environmental problem. One way to recycle wasted PET bottles is grinded into irregular fiber. Then, it was incorporate with the concrete and test the performance of the concrete. The study was conducted using cylindrical mold of concrete to investigate the performance of the concrete in term of mechanical properties. A total of four batches of concrete were produced namely, normal concrete and concrete containing PET fiber of 0.5%, 1.0% and 1.5% fraction volume. In this research, the mechanical properties that were measured are compressive strength, splitting tensile strength and modulus of elasticity (MOE) following British Standard method. The results revealed that the presence of PET fiber in concrete will increase the concrete performance. Nevertheless, the content of PET fiber was specified in a specific limit to avoid effect of concrete strength.

Performance of Concrete Using Light Waste PET Fibre

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).

Deflection Behaviour of Irregular-Shaped Polyethylene Terephthalate Fibre Reinforced Concrete Beam

This paper reports the results on deflection behaviour of reinforced concrete (RC) beam conducted using irregular-shaped Polyethylene Terephthalate (IPET) as a fibre. Three volume fraction of IPET fibre is used namely, 0.5%, 1% and 1.5%. All RC beam specimens are tested under four point loading under flexural capacity behaviour. The results for deflection behaviour namely cracking stage, yield stage and ultimate stage and ductility are reported. The results than are compared with control RC beam. It is found that the addition of IPET fibre improves the first crack and ultimate strength as well as ductility of RC beams proportional to the increment of volume fraction of IPET fibre. Therefore, based on the results reported, the addition of IPET fibre significantly increases the deflection behaviour of RC beam.

Cracking Propagation of Reinforced Concrete Using Polyethylene Terephtalate (PET) Bottles as Fine Aggregate

This paper describes the experimental investigation on the cracking propagation and pattern of reinforced concrete beam containing PET aggregate as fine aggregate that subjected to shear. The replacement ratio of 25%, 50% and 75% were used in this study. Prior to structural test, the materials properties which include the compressive strength test, split tensile test, Modulus of Elasticity test and density were determined. The result obtained showed that the inclusion of PET aggregate reduce the initial loading cracks to 27%, 38% and 46% compared to their corresponding normal concrete ; thus affecting the shear resistance of the structural beam especially the ability of the beam to resist shear via interface friction and interlocking between aggregate.

Development of mix design nomograph for polyethylene terephthalate fiber concrete

The aim of this project was to develop of mix design nomograph for PFC that can be used for estimated the required compressive strength and splitting tensile strength with the required PET and water-cement-ratio.The fibers were prepared by using plastic granulator machine SLM 50 FY with size passing 10 mm and retained 5 mm sieve. Different volumes percentages of PET fibers with 0%, 0.5%, 1.0% and 1.5%, were introduced in concrete mixes. The specimens prepared for this study was cylinder concrete with 100 mm diameter and 200 mm height. The laboratory work for physical properties were focused on density and workability, meanwhile for mechanical properties were focused on compressive strength, splitting tensile strength and modulus of elasticity of PET fiber concrete (PFC). The experiment results indicate that the addition of PET fibers significantly decreased the compressive strength and splitting tensile, however the compressive strength still can be acceptable since achieved the mix design The nomograph developed can be used to estimate the desired compressive, splitting tensile strength as well as the modulus of elasticity (MOE).

Cracking Propagation and Pattern Behaviour of Irregular-Shaped Polyethylene Terephthalate Fibre Reinforced Concrete Beam

This paper reports the results on cracking propagation and pattern of reinforced concrete (RC) beam conducted using irregular-shaped Polyethylene Terephthalate (IPET) as a fibre. Three volume fraction of IPET fibre is used namely, 0.5%, 1% and 1.5%. All RC beam specimens are tested under four point loading under flexural capacity behaviour. Prior to structural test, the materials properties which include the compressive and tensile strength test and modulus of elasticity test were determined. The results than are compared with control RC beam. It is found that the RC beam with IPET fibre does not significantly change the behaviour of failure mode, cracking propagation and pattern compared to control RC beam.
