Análise das propriedades mecânicas do concreto com adição de seixo e polietileno tereftalato (PET). Revista de Gestão e Secretariado – GeSec, São José dos Pinhais, PR, v. 16, n. 2, p. 01-14, 2025. DOI: 10.7769/gesec.v16i2.4530.https://rigalileo.itegam.org.br/handle/123456789/380The increasing accumulation of plastic waste, particularly PET, represents a significant environmental challenge due to its long degradation time and the negative impacts of improper disposal. This study explores the feasibility of partially replacing sand with ground PET in concrete, focusing on its effects on compressive strength and workability. Four concrete compositions were tested: one without PET and three with 10%, 30%, and 50% PET, adhering to ABCP standards. The results demonstrated that PET addition, in certain proportions, maintained the required strength while reducing environmental impacts, highlighting the sustainable potential of recycled PET in construction.pdf.Polietileno Tereftalato (PET)ReciclagemConcreto SustentávelPropriedades MecânicasMeio AmbienteArtigo científicoEngenharia Civil
