中文摘要

本文首先以電廠飛灰利用鹼活化處理技術,製作成無機聚合物綠色膠結料,本研究主要採用鹼當量(AE)6%、8%及10%,鹼模數比(Ms)1.0、1.5、2.0與液膠比(W/B)0.4、0.5及0.6等配比,其中水淬爐石粉/F級火力電廠飛灰比例分別為S20F80、S40F60、S60F40、S80F20等調配,並製作5cm×5cm×5cm之立方體試體,經養護3天、7天及28天,探討其抗壓強度、吸水率、乾縮量和凝結時間等關係,並求出最佳配比,並選出較佳配比製作成無機聚合物綠色水泥。試驗結果顯示:(1)針對6%、8%及10%鹼當量範圍,鹼模數比為1.5及2.0,液膠比為0.5、0.6的條件下,以S20F80、S40F60等混拌配比的電廠飛灰無機聚合物,終凝時間即符合水泥規範要求。(2)針對6%、8%及10%鹼當量範圍,鹼模數比為2.0,液膠比為0.4的條件下,以S20F80、S40F60、S60F40、S80F20等混拌配比電廠飛灰無機聚合物抗壓強度已經達到普通水泥(Type I)抗壓強度之要求。(3)針對6%、8%及10%鹼當量範圍,鹼模數比為1.0、1.5、2.0,液膠比為0.4的條件下,以S20F80、S40F60、S60F40、S80F20等混拌配比吸水率最低。吸水率會隨著鹼當量提高而下降,隨著養護時間增加而降低。(4)針對6%、8%及10%鹼當量範圍,並控制其鹼模數比為1.0、1.5、2.0,液膠比為0.4的條件下,以S20F80、S40F60、S60F40、S80F20等混拌配比乾縮量最低。(5)針對6%、8%及10%鹼當量範圍,鹼模數比為1.0,液膠比為0.6的條件下,以S20F80、S40F60、S60F40、S80F20等混拌配比電廠飛灰無機聚合物,凝結時間最短。

英文摘要

First in this study used of alkali activation technology to manufacture of geopolymer green cement made from power plant fly ash, its mixing main ratios: (1)alkali equivalent(AE) was set to 6%, 8% and 10% ,(2) alkali modulus ratio (Ms) was set to1.0,1.5 and 2.0,(3) liquid binder ratio(W/B), such as the deployment of 0.4,0.5and 0.6, among them, slag powder / F-class power plant fly ash ratios respectively had S20F80、S40F60、S60F40、S80F20 etc., mixing production 5cm * 5cm * 5cm test samples, cured 3 days, 7 days and 28 days after, investigated the relationship between compressive strength, water absorption, dry shrinkage and setting time, taked the best ratio used as geopolymer green cement. From the experimental results show (1)against 6%,8%,10% alkali equivalent range, alkali modulus ratio (MS) was set to1.0,1.5 and 2.0, liquid binder ratio was set to0.5 and 0.6 condition, base S20F80、 S40F60 mixed ratios of plant fly ash geopolymer, the final setting time met the requirements of cement specifications, (2) against 6%,8%,10% alkali equivalent range, alkali modulus ratio (MS) was set to 2.0, liquid binder ratio was set to0.4 condition, base S20F80、S40F60、S60F40、S80F20 mixed ratios of plant fly ash geopolymer , compressive strength met the requirements of cement specifications, (3) against 6%,8%,10% alkali equivalent range, alkali modulus ratio (MS) was set to 1.0,1.5 and 2.0, liquid binder ratio was set to0.4 condition, base S20F80、S40F60、S60F40、S80F20 mixed ratios of plant fly ash geopolymer ,they had the lowest water absorption, water absorption decreases with equivalent alkali increase, decreases with curing time increase,(4)against 6%,8%,10% alkali equivalent range, alkali modulus ratio (MS) was set to 1.0,1.5 and 2.0, liquid binder ratio was set to0.4 condition, base S20F80、S40F60、S60F40、S80F20 mixed ratios of plant fly ash geopolymer ,they had the lowest dry shrinkage, (5)against 6%,8%,10% alkali equivalent range, alkali modulus ratio (MS) was set to 1.0, liquid binder ratio was set to0.6 condition, base S20F80、S40F60、S60F40、S80F20 mixed ratios of plant fly ash geopolymer ,they had the lowest setting time.
