Application of fibres from recycled PET bottles for concrete reinforcement
Daniel Wiliński , Paweł Łukowski , Gabriel Rokicki
AbstractWaste PET can be reused as partial or complete substitute of an aggregate in a concrete composition or as a concrete reinforcement. However, the main drawback of such applications is the hydrolysis of ester linkages of poly(ethylene terephthalate) in highly alkaline environment of the cement matrix. To prevent alkaline hydrolysis, the PET fibres were coated with commercially available ethylene/vinyl acetate copolymer (EVA). Effectiveness of the use of copolymer EVA as a protection layer against strong alkali solutions has been demonstrated and discussed. Chemical changes in PET fibres after alkaline treatment have been referred to mechanical properties of the fibres. Mechanical properties, like compressive and flexural strength of the composites as well as the long-term durability performance of recycled PET fibres in alkaline environment were also investigated. The preliminary results indicated that the introduction of the PET fibres does not deteriorate the mechanical strength of the concrete composite.
