This approach is essential to promote sustainability and mitigate environmental impacts, especially in a sc enario where pollution levels are alarmingly high. The use of renewable raw materials offers the advantage of being replenishable, ensuring their availability when needed. To address environmental challenges, this study presents an innovative solution: the synthesis of a geopolymeric cementitious mixture based on alkali activated materials (AAM). This solution not only demonstrates promising mechanical performance but also contributes to the conservation of natural resources. Specifically, this work propose s the creation of geopolymeric tiles with varying percentages of polyester fiber, using a formulation process that includes metakaolin, blast furnace slag, sodium hydroxide alkaline solution, silicate, and polyester fiber. The research methodology involved creating fifteen small scale tiles using a polypropylene fibrocement mold at a 1:10 scale, with dimensions of 11 cm x 24 cm x 6 mm thickness. The tiles were manufactured with 0%, 0.5%, 1%, 2%, and 3% by mass of sustainable cement, allowing for an evaluati on of the influence of this incorporation. The tests conducted included tensile and flexural strength assessments, as well as characterization through Scanning Electron Microscopy (SEM), X Ray Diffraction (XRD), and Fourier Transform Infrared Spectroscopy (FTIR). The results revealed that increasing fiber concentrations influences the integrity of the test specimens. From the mixture containing 3% fiber onward, the concentration of the alkaline activator proved insufficient, leading to the appearance of man y unreacted particles and a decline in mechanical strength. It can be concluded that the raw materials used are suitable for application in geopolymers. With polyester fiber content up to 2%, mechanical strength is adequate for use, and the material shows great potential for application in the cement industry.Acesso AbertoTelhas de fibras sintéticasDesempenho mecânicoAnálise microestruturalSynthetic fiber tilesMechanical performanceMicrostructural AnalysisCNPQ::ENGENHARIAS::ENGENHARIA DE MATERIAIS E METALURGICA::MATERIAIS NAO METALICOS::POLIMEROS, APLICACOESTrabalho de Curso - Graduação - MonografiaAttribution-NonCommercial-NoDerivs 3.0 Brazil
