Avaliação comparativa do desempenho do concreto convencional e do concreto com substituição do agregado miúdo por segregado de brita ecológica na Amazônia.

Disponível em: https://bdm.ufpa.br/handle/prefix/9602https://bdm.ufpa.br/handle/prefix/9602The increasing generation of plastic waste and the extraction of natural aggregates intensify environmental impacts in the construction industry. In this context, a 100% eco-friendly material was developed in the Amazon region, and its feasibility and performance in cementitious matrices were evaluated in this study.The main objective of this research is to analyze and compare the compressive strength and water absorption by capillarity of concrete produced with partial and total replacement of fine aggregate by a segregated fraction of this material, at different replacement levels, in comparison with conventional concrete. For this purpose, five concrete mixtures were produced: one reference mix and four with 25%, 50%, 75%, and 100% replacement of the ecological material. The concrete with replacement presented results demonstrating that it can be used for the manufacture of non-structural elements, showing capillary water absorption values close to those of conventional concrete.Acesso AbertoSustentabilidadeMateriais alternativosTermoplásticosHabitações de baixo custoSustainabilityAlternative materialsThermoplasticsLow-cost housingCNPQ::ENGENHARIAS::ENGENHARIA CIVILTrabalho de Curso - Graduação - Artigo
