Abstract Scope |
Geopolymers are eco-friendly materials that efficiently replace cementitious and ceramic materials. In this context, the objective of this work was to carry out the production of geopolymer tiles using commercial metakaolin and flue gas desulfurization waste (FGD). The tiles were produced in the molar ratio SiO2/Al2O3=3.00, using a composition with 0, 10 and 20% substitution of metakaolin by FGD. Prismatic specimens were produced, with tests of tensile strength, mass density, water absorption and linear shrinkage being carried out. Curing was carried out at 25ºC and 65ºC for a period of 7 days. The results obtained demonstrate that the use of FGD improved the mechanical behavior of the tiles, due to the formation of phases different from geopolymerization of metakaolin alone. It is concluded that the application of geopolymer tiles with FGD is viable, as the values obtained are compatible with the proposed application. |
