Abstract Scope |
Geopolymers have been widely studied due to their potential to replace Portland cement. These materials are considered less aggressive to the environment, because of the lower emission of carbon dioxide. In order to make the product more sustainable and solve the problem of incorrect disposal of solid wastes, the purpose of this work was the evaluation of alkali-activated pastes produced from chamotte and waste glass. Four types of sodium hydroxide (NaOH) solutions with molar concentration of 8 mol/L were prepared, with the addition of 0, 5, 10 and 15g of waste glass per 100ml of NaOH solution. Flexural and compressive strength tests were performed, as well as the microstructural characterization. The results showed that the waste glass improved the mechanical strength of the geopolymer. It can be applied as an alternative activator, acting as an extra source of soluble silica. |
