| Abstract Scope |
The ornamental stone industry has shown exponential global growth. However, along with such production, its powdered waste has also been generated in large amounts. When the waste does not have a correct destination, it causes problems for human health and pollution on river slopes. Therefore, a sustainable alternative for the disposal of granite waste is the addition in geopolymeric binders. This research aimed to evaluate the technical feasibility of geopolymers produced with granite waste as precursor. The physical, chemical and mineralogical properties of the residue were investigated. A mechanical activation process was applied to the waste, in order to improve its reactivity. Geopolymers were produced with granite waste and metakaolin as precursors, and sodium hydroxide as activator. Different proportions were investigated through a factorial design of experiments. The mechanical and microstructural properties of the samples were obtained, aiming to assess the potential of the binders for application in civil construction. |
