Acesso em:.https://bdm.ufpa.br/handle/prefix/9611The civil construction sector is one of the primary carbon emitters and producers of solid waste, driving the search for alternative materials and sustainability strategies. Within this context, Polyvinyl Chloride (PVC) presents a global challenge due to its slow and difficult environmental degradation, despite being a highly recyclable material. This research evaluated the technical feasibility of rendering mortars incorporating PVC waste (10%, 20%, and 30%) as a replacement for fine aggregate. Due to the hydrophobic nature of the polymer, 5 workability required an increase in the w/c ratio to maintain consistency. The composites exhibited a reduction in bulk density as the polymer content increased, resulting in a decrease of approximately 31% in the AR-PVC30 mortar, which enabled them to be classified as lightweight mortars. In the hardened state, although the 20% content showed a peak in capillary absorption, the 30% waste mix exhibited a reduction in this coefficient, suggesting that the repellent nature of PVC may hinder water transport within the matrix at high concentrations. Additionally, there was a sharp reduction in flexural tensile strength, which declined from 3,95 MPa in the reference mix to 1,38 MPa in the 30% replacement mix. It is concluded that the use of PVC waste is a technically viable and environmentally responsible alternative for non-structural purposes.Acesso AbertoArgamassaPolímeroResíduoPolicloreto de Vinila (PVC)SustentabilidadeMortarPolymerWastePolyvinyl Chloride (PVC)SustainabilityCNPQ::ENGENHARIAS::ENGENHARIA CIVILTrabalho de Curso - Graduação - Artigo
