| Abstract Scope |
The global growth of the ornamental stone industry has led to increased waste generation, often without proper destination, causing environmental and health issues. A sustainable alternative is using residues like granite in geopolymer production, due to their high silicon and aluminum content and potential to replace traditional cementitious materials, reducing carbon dioxide emissions. The main objective of this study is to evaluate the behavior of geopolymeric pastes, produced with the addition of granite waste, in terms of their durability under natural conditions. The mechanical properties and durability of geopolymer mixtures using granite waste and metakaolin as precursors were evaluated, with sodium hydroxide (NaOH) used as the activator. Mechanical properties were assessed through compression and flexural strength tests, while durability was analyzed through firing tests and wetting–drying cycles. Preliminary results show that the strength is higher for mixtures with 10 mol/L NaOH and 20% granite. |
