Among these materials, ground glass waste stands out for its availability, chemical stability, and high amorphous silica content, characteristics that justify its investigation as a partial substitute for fine aggregate in mortars. The objective of this study was to evaluate the physical, mechanical, and microstructural behavior of mortars in which sand was partially replaced by glass waste at levels of 10%, 20%, 30%, and 40% by mass. Initially, the physical characterization of the raw materials was carried out, verifying that glass presents greater fineness and angularity compared to natural sand, factors that directly influence the compaction and water demand of the mixtures. The granulometric analysis confirmed the predominance of fine particles in the waste, while the determination of specific gravity indicated values compatible with those of fine aggregates used in civil construction. In the fresh state, it was observed that increasing the glass content led to longer setting times, a consequence of the low water absorption and lower initial reactivity of the vitreous material. In physical tests, there was a reduction in water absorption and void index, as well as a slight increase in specific gravity, indicating greater densification of the cementitious matrix. Compressive strength showed significant improvement at intermediate contents, especially at 20% and 30%, due to the filling effect of fine glass particles and the late pozzolanic contribution of amorphous silica. The 30% content showed the best overall performance, combining higher mechanical strength, lower porosity, and a more compact microstructure. Scanning electron microscopy images showed matrix refinement and the presence of hydrated products associated with the interaction between cement and glass particles. Statistical analysis (ANOVA and Tukey's test) confirmed significant differences between the groups, consolidating the 30% content as the most efficient condition. The results obtained show that the partial replacement of sand with ground glass is technically feasible up to 30%, providing relevant improvements in material performance and contributing to more sustainable practices in civil construction.Acesso AbertoArgamassaResíduo de vidroPropriedades mecânicasCaracterização físicaMortarGlass wasteMechanical propertiesPhysical characterizationCNPQ::ENGENHARIAS::ENGENHARIA DE MATERIAIS E METALURGICA::METALURGIA DE TRANSFORMACAO::TRATAMENTO TERMICOS, MECANICOS E QUIMICOSTrabalho de Curso - Graduação - MonografiaAttribution-NonCommercial-NoDerivs 3.0 Brazil
