Application of Recycled PET Fibers for Concrete Floors

Abstract

High consumption of plastics leads to production of large amounts of plastic waste. Plastic is non-biodegradable so its disposal has been a problem. In order to resolve this problem, recycled PET fibers were proposed to be used as reinforcement in concrete. This paper has discussed the effect of adding Polyethylene terephthalate (PET) fiber to the blended cement mixed concrete floor slab panel. This research consists of two main stages. In first stage, different volumes of recycled PET fibers, i.e. 0%, 0.5%, 1.0% and 1.5% have been added as percentages of concrete by volume. The results showed that the maximum volume of PET fiber for a desired compressive and tensile strength was 1.0%. It was observed that 15.3 % of increase in compressive strength, 22.44% of increase in flexural strength and 18.77% of increase in split tensile strength for the addition of 1.0% PET fibers to the concrete. In second stage, optimum fiber percentage (1.0%) selected from the first stagewas used to produce slab panels. Inorder to investigate the structural performances of the slab panel, center-point line loading test, dropping weight test and energy absorption test were conducted. It has been found that recycled PET fiber introduced slab panels showed better performance compared to the conventional floor slab panel.

Physical, mechanical, and durability properties of concrete containing different waste synthetic fibers for green environment – A critical review

“…Nasr et al [ 43 ] reported that 0.25 % of waste plastic fiber improved strength by 16.8 % and 21.5 % at the concrete age of 28 and 56 days. However, the increase in synthetic fiber content in the concrete mixture can reduce linearly the concrete compressive strength [ 76 , 77 ]. Abdulridha et al [ 62 ] investigated the effect of reinforcing the concrete by waste nylon fiber from the rope wire by 0 %, 0.25 %, 0.5 %, and 1 % to the weight of the concrete mixture and found that the replacement of waste rope fiber by 0.5 % improves compressive strength by 22 % compared to the control mixture.…”

Compressive and Thermal Properties of Non-Structural Lightweight Concrete Containing Industrial Byproduct Aggregates

“…Among all of the plastic materials, polyethylene terephthalate (PET) is one of the main recycled materials used to perform thermal insulation in buildings [ 56 ]. Many authors have already investigated the suitability of plastic waste in cement and/or concrete [ 57 , 58 ]. It is clear that the use of this type of waste in the construction field may represent an effective solution for reducing the environmental impact of plastics and, thus, to contribute to the development of an increasingly sustainable building industry.…”

New Mortar Mixes with Chemically Depolymerized Waste PET Aggregates

“…However, what makes PET so important, among the plastics used as reinforcement for concrete, is its recyclability together with the great abundance of postconsumer waste in the form of bottles. e presence of fibres improves the tensile behaviour of concrete thanks to the sewing effect that they have on the cracks [14]. eir action, in fact, is more effective in the postcracking phase, preventing and reducing the propagation of cracks.…”
