超硫酸鹽水泥(Super Sulfate Cement，SSC)基膠結材料因其晚期強度高且水泥使用量低而被使用，但凝結時間過長，因此本研究分為前導試驗及後續試驗，前導試驗選用水膠比(W/B)0.4不同燒結溫度50°C、100°C、400°C及900°C之排煙脫硫石膏(Flue Gas Desulfurization Gypsum，FGDG)進行比較，後續試驗選用不同水膠比(W/B)0.3、0.4、0.5，使用飛灰以不同取代量(RM) 0%、5%、10%、15%、20%、25%及30%，以飛灰取代爐石粉製成超硫酸鹽水泥漿體，探討其工程性質之影響，評估含飛灰之超硫酸鹽水泥漿體之可行性。
研究結果顯示：(1)燒結溫度為50oC之排煙脫硫石膏其成分為二水石膏，燒結溫度為100oC之排煙脫硫石膏其成分為半水石膏，燒結溫度為400oC之排煙脫硫石膏其成分為半無水石膏，燒結溫度為900oC之排煙脫硫石膏其成分為無水石膏；就坍流度而言，50oC及900oC為最佳；就凝結時間而言，400oC為最佳；就抗壓強度而言，400oC為最佳；(2)當飛灰取代量由0%提升至30%時，SSC漿體之工程性質，包含抗壓強度、抗彎強度及抗拉強度皆有先下降後提升之趨勢，水膠比0.3之配比，飛灰取代量由0%提升至30%之7天抗壓強度降低了19.36%，到了28天抗壓強度提升了30.96%，7天抗彎強度降低了59.26%，28天抗彎強度提升了46.34%，7天抗拉強度降低了54.17%，到了28天抗拉強度提升了38.46%。
綜上所述，以飛灰取代爐石粉25%為最佳配比，可提升SSC之工程性質。

Super Sulfate Cement (SSC)-based cementing material is used because of its high late strength and low cement usage, but the setting time is too long. Therefore, this study is divided into pilot test and follow-up test. The pilot test uses water cement Flue Gas Desulfurization Gypsum (FGDG) with a ratio (W/B) of 0.4 and different sintering temperatures of 50°C, 100°C, 400°C and 900°C were compared, and different water-binder ratios ( W/B) 0.3, 0.4, 0.5, using fly ash with different replacement amounts (RM) 0%, 5%, 10%, 15%, 20%, 25% and 30%, using fly ash instead of furnace stone powder to make super Sulphate cement slurry, discuss the influence of its engineering properties, and evaluate the feasibility of ultra-sulphate cement slurry containing fly ash.
The research results show that: (1) The FGD gypsum with a sintering temperature of 50oC is composed of dihydrate gypsum; The composition of gypsum is semi-anhydrous gypsum, and the composition of flue gas desulfurization gypsum with a sintering temperature of 900oC is anhydrous gypsum; in terms of slump fluidity, 50oC and 900oC are the best; in terms of setting time, 400oC is the best; In terms of compressive strength, 400oC is the best; (2) When the amount of fly ash replacement increases from 0% to 30%, the engineering properties of SSC slurry, including compressive strength, flexural strength and tensile strength, are all improved. The trend of increase after the decline, the water-cement ratio of 0.3, the 7-day compressive strength of fly ash replacement increased from 0% to 30% decreased by 19.36%, and the 28-day compressive strength increased by 30.96%. The flexural strength decreased by 59.26%, the 28-day flexural strength increased by 46.34%, the 7-day tensile strength decreased by 54.17%, and the 28-day tensile strength increased by 38.46%.
To sum up, the best ratio is to replace 25% of the furnace stone powder with fly ash, which can improve the engineering properties of SSC.
