Waste polyethylene terephthalate as an aggregate in concrete

Abstract: 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 develop… Show more

“…increases, the density and elastic modulus of concrete or mortar are apparently reduced [16][17][18][19][20][21][22][23]. As for the mechanical properties, the compressive strength, splitting tensile strength and flexural tensile strength decrease with an increase in plastic content [16][17][18][19][20][21][22][23][24][25][26] mainly due to the mismatch properties between plastic particles and cement paste [19]. For plastic with non-absorption properties, internal bleeding water would accumulate and surround the plastic particles resulting in a relatively weak bond between the particles and cement paste [22].…”

“…Tendo em vista os materiais potencialmente recicláveis no contexto urbano, o reciclado de polietileno tereftalato (PET) já vem sendo utilizado em diversos segmentos industriais, porém ainda pouco empregado na construção civil, como revela um censo realizado pela Associação Brasileira da Indústria do PET (ABIPET) em 2011 [2]. Nessa perspectiva, o presente trabalho avaliará a eficiência do Poli (tereftalato de etileno), PET, como um agregado substituto na fabricação de pavers, pavimento intertravado com peças de concreto, largamente utilizado para a construção de pavimentos flexíveis urbanos, devido a características como durabilidade e facilidade de manejo, além de dispensar equipamentos especiais e de grande porte, o que leva a um menor tempo de construção e a consequente liberação ao tráfego imediato [3,4]. Diante do exposto, a pesquisa então se justifica pela importância de se aliar construção civil à sustentabilidade, em busca de novos métodos e insumos recicláveis, sem que se percam características importantes à qualidade destes artefatos e reduzindo custos.…”

“…Le choix des matériaux utilisés a une répercussion directe sur la consommation en matières premières et en énergie [1,2]. Ainsi, l'utilisation de matières premières alternatives, comme les déchets plastiques exemple le polyvinyle de chlorure (PVC) [3], PET [4][5][6][7][8][9][10], les fibres de PET [11], le polyéthylène à haute densité (PEHD) [12], de la mousse de polyuréthane rigide [13], apporterait une réponse au problème d'épuisement des ressources naturelles.…”
