“…The percentage reduction of compressive strength was also compared with the percentage reductions of flexural strength with respect to the reference concrete, as presented in Figure 7. As in the Hannawi et al study (2010), the reduction in compressive strength with respect to the reference concrete was greater than the reduction observed in the flexural strength 8 . This difference is more pronounced for concrete with PC, which is coarser and flakier than the other two PET-aggregates.…”

“…Different types of plastic waste have been used as aggregate, filler or fibre in cement mortar and concrete after mechanical treatment. They include: polyethylene terephthalate (PET) bottles, polyvinyl chloride, PVC pipes, high density polyethylene, HDPE, thermosetting plastics, mixed plastic waste, expanded polystyrene foam, polyurethane foam, polycarbonate, and glass reinforced plastic [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] . The details about the generation of PA as well as the properties of concrete containing PA are presented in a recent review 22 .…”

This paper reports the strength behaviour of concrete containing three types of recycled polyethylene terephthalate (PET) aggregate. Results are also analysed to determine the PET-aggregate's effect on the relationship between the flexural and splitting tensile strengths and compressive strength and to know whether the relationships between compressive strength and other strength characteristics given in European design codes are applicable to concrete made with PET-aggregates. The compressive strength development of concrete containing all types of PET-aggregate behaves like in conventional concrete, though the incorporation of any type of PET-aggregate significantly lowers the compressive strength of the resulting concrete. The PET-aggregate incorporation improves the toughness behaviour of the resulting concrete. This behaviour is dependent on PET-aggregate's shape and is maximised for concrete containing coarse, flaky PET-aggregate. The splitting tensile and flexural strength characteristics are proportional to the loss in compressive strength of concrete containing plastic aggregates.

Fresh, Mechanical and Absorption Characteristics of Self-Consolidating Concretes Including Low Volume Waste PET Granules

This study evaluates the effect of waste polyethylene terephthalate (PET) granules on the fresh, mechanical and absorption characteristics of self-consolidating concretes (SCCs). Fine aggregates were replaced with different percentages (from 0% to 8%) of PET granules obtained by crushing waste PET bottles. The fresh properties of SCC containing PET granules were determined using slump flow and V-funnel flow time tests. Mechanical properties (compressive strength and splitting tensile strength tests) and absorption properties (sorptivity and water absorption tests) were evaluated. The results indicated that utilization of waste PET granules in production of SCC could be an effective way for recycling purpose. The maximum amount of PET replacement should be limited to 5%. Exceeding 5% of PET content may result in an increase of V-funnel flow time to overpass the limiting value, decrease in compressive strength, reduction in sorptivity and increase in the water absorption. The production of high performance SCC containing 5% PET granules satisfies all the requirements for SCC with satisfactory outputs.

“…A well-known lightweight plastic material with a low density and porosity is Polyethylene terephthalate (PET) (Hannawi et al, 2010). PET is a thermoplastic polymer that has been used in a variety of products due to its lightweight characteristics, ease of handling and storing.…”

“…PET wastes have been recently considered as lightweight aggregates for cementitious composites (Satapathy and Nando, 2008) in civil engineering. The PET residues can also be used as matrix in laminates (Onal and Adanur, 2005) and particulate composites (Hannawi et al, 2010). Modro et al have investigated the effect on the mechanical strength of Portland cement concrete when adding PET waste, observing a reduction in strength for increasing volume fraction of PET aggregates (Modro et al 2009).…”

This work investigates the mechanical behaviour of cementitious composites (mortar) when quartz inclusions are totally or partially replaced with polyethylene terephthalate (PET) particles. A full factorial design is performed to identify the effect of the water/cement ratio and the range of quartz particles size used in the replacement on the different mechanical and physical parameters (bulk density, apparent porosity, water absorption, oxygen permeability, compressive strength and modulus of elasticity). The results show a general reduction of the mechanical properties when the replacement with quartz particles is put in place. The composites made by replacing the coarse quartz particles showed acceptable mechanical properties for non-structural civil engineering applications, with a significant amount of PET recycling to be used as aggregates for some specific end-user cases.
