| Abstract Scope |
In recent decades, the rapid growth of industrial production has significantly increased the amount of industrial waste, posing considerable environmental challenges. One such waste, FGD gypsum, generated in the desulfurization process of combustion gases in thermal power plants, presents potential for sustainable reuse to mitigate environmental impacts. The objective of this study is to evaluate the impact resistance of epoxy composites with different proportions of FGD gypsum. This study investigated the feasibility of incorporating FGD gypsum into epoxy systems, with 0, 10, 20, 30 %vol. The impact test was of the Izod type, carried out according to procedures established by ASTM D256. The results were analyzed using analysis of variance and Tukey test, aiming to verify whether the effects were significant. Through this work it is possible to observe the influence of the addition of residues in epoxy systems, as well as investigate the effects on impact resistance. |
