With this growing demand, the environmental impacts caused by civil construction are also growing and the search for innovative studies is necessary as an alternative for a more sustainable concrete. This work aimed to develop the study of the microscopy of high performance alternative pastes and mortars, from alkali-activated clay minerals with blast furnace slag. The materials used in the work were: metakaolin, blast furnace slag, Potassium Hydroxide and sand as fine aggregate. The methodology used to obtain the formulations for making paste was using the studies of Porto (2019) and Silva (2011) while for the mortar were the studies of Helene and Terzian (1993) and Silva (2011). 5 CP's were made for each paste formulation where the mass amount of slag is varied (0.35%, 45%, 55%, 60% and 65%) and 5 CP's for each mortar formulation with 45% slag and varying the mass amount of sand (0%,29%,59%,69%,75% and 81%). The tests performed were mineralogical characterization of the raw material by XRD, setting time and optical microscopy. In the results, it can be seen that the setting time is influenced by the concentration of the alkaline activator, where the results were not similar to those in the literature. From the paste with 45% EAF, the concentration of the alkaline activator is not sufficient, which leads to the appearance of many unreacted particles, as for the mortar it was observed that with the increase in the amount of sand, there was a concentration of particles that was attributed the manufacturing process and the concentration of the alkaline activator due to the amount of loose and unreacted particles. It can be concluded that the raw materials used are suitable for use in geopolymers, with the increase of EAF the amount of micropores decreased in the paste and that the material used has great potential in the cement industry.Acesso AbertoSustentávelMetacaulimEscóriaMicroscopiaSustainableMetakaolinSlagMicroscopyCNPQ::ENGENHARIAS::ENGENHARIA DE MATERIAIS E METALURGICA::MATERIAIS NAO METALICOS::CERAMICOSTrabalho de Curso - Graduação - Monografia
