ResumenPrevious studies conducted by this research team have proven that fired ceramic wastes can be viably used as an alternative prime material in Portland cement clinker manufacture. Chemical analysis of the resulting clinkers revealed greater amounts of ZnO, ZrO2 and B2O3 than found in conventional Portland cement clinker, as well as a higher β-C2S content. In addition, α’HC2S was observed to stabilize, due primarily to the presence of B2O3. The present study aimed to obtain more highly reactive belite cement clinkers made with ceramic wastes and to ascertain their reactivity and stability when CaSO4·2H2O was added to the raw mix. The findings showed that the addition of ceramic wastes and gypsum had no effect on clinker reactivity or burnability. Despite the high C2S content found in these clinkers (20-60%), their hydration rates were comparable to hydration reaction times in conventional Portland cements.
