試驗采用低溫合成方法將高鈣固硫粉煤灰制成低溫合成粉煤灰水泥熟料,采用XRD分析、力學性能測定等測試方法研究其物相及性能。試驗表明高鈣固硫粉煤灰低溫合成熟料的膠凝礦物主要為C12A7、β-C2S、CA,將其與硅酸鹽熟料、二水石膏復合,可制得具有良好性能的高鋁水泥-硅酸鹽水泥-石膏系統的復合水泥。
關鍵詞:低溫合成;高鈣固硫粉煤灰;復合水泥
Abstract: The experiment was done by adopting low temperature synthesis to make high calcium and solid sulfate fly ash into low temperature synthetic fly ash cement clinker and by applying XRD analysis and mechanical property determination to study its physical phase and performance. It shows that C12A7、β-C2S、CA are the main gel minerals of the produced clinker and well performance high aluminium cement-Portland cement-gypsum system can be produced by compounding it with Portland clinker and dehydrate gypsum.
