摘要: Previous 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 ZnO, ZrO2 and B2O3 than found conventional clinker, well a higher β-C2S content. In addition, α’HC2S was observed to stabilize, due primarily presence B2O3. The present study aimed obtain more highly reactive belite made with ascertain their reactivity stability when CaSO4·2H2O added raw mix. findings showed addition gypsum had no effect on or burnability. Despite high C2S content these (20-60%), hydration rates were comparable reaction times cements.
