Este trabalho tem como objetivo avaliar a hidratação na idade inicial de cimentos YCC produzidos a partir do coprocessamento do SFCC. Para isso, foram produzidos seis clínqueres com diferentes teores de ye’elimita, com e sem SFCC. Estes foram caracterizados por DRX/Rietveld. As pastas foram avaliadas por TG/DTG e DRX/Rietveld para compreender o mecanismo de hidratação no terceiro dia destes cimentos. Foi possível sintetizar as principais fases dos YCC, nos clínqueres com e sem SFCC. Além disso, na idade avaliada, as pastas com e sem SFCC apresentaram composição de fases comparáveis indicando o potencial de coprocessamento deste resíduo.
