Abstract:
In recent years, research has been generated around the development of geopolymers to replace Portland cement in the construction industry, mainly due to its cementitious properties, which would be a very promising solution for the building market. From the studies and articles published, it is possible to observe the environmental and energy advantages that they provide, compared to the cements currently used. Alkaline activation will occur with materials rich in aluminosilicates, making it possible to observe the opportunity for the use of materials discarded in the manufacturing processes of other companies to gain a new use, which generates enormous environmental and economic gains. Fly ash is an industry waste that is still underutilized, with irregular discards that harm the environment. According to its chemical composition and published studies, there is the possibility of its use as a precursor in alkali-activated materials. Therefore, the objective of this work was to evaluate the possibility of using fly ash as a precursor in geopolymers, varying the compositions used for the formulation of mortars and the curing temperature.
