The objective of this research is to evaluate the influence of incorporating kraft paper fibers, obtained from the recycling of cement bags, on soil behavior, comparing this approach with the use of cement. Additionally, the study aims to analyze the feasibility of recycling cement bags, utilizing their fibers as a sustainable solution for construction waste. To achieve this, the methodology involves studying two types of soil with distinct characteristics—one more sandy and the other more clayey—through laboratory tests. These tests will be conducted with and without the addition of materials (Portland cement and kraft paper fibers) in different percentages to evaluate the impacts of these incorporations. The characterization included granulometry, sedimentation, and compaction tests. The results indicate that in the compaction tests, the specimens with the addition of cement showed slightly higher maximum dry bulk density values (γdmax) compared to those with the addition of kraft paper fibers. It was concluded that in the compaction tests with 4% and 8% of fibers and cement, no significant improvements in the soil's physical properties were observed with the addition of kraft paper fibers compared to the soil improved with cement. However, the addition of fibers did not negatively affect the evaluated soil properties, such as the optimum moisture content (wótima). Considering that this waste requires a sustainable destination, incorporating the fibers into the soil could be a viable alternative for environmentally responsible disposal of this material.ptEngenharia CivilResíduos – Construção civilConstrução sustentávelFibras – IncorporaçãoConstruction WasteFibers - IncorporationTrabalho de Conclusão de CursoENGENHARIAS::ENGENHARIA CIVIL
