本研究探討三種液固比(0.45、0.5、0.55)、三種矽酸鈉溶液(水玻璃)模數(1.5、2.0、2.5)、三種比率硼砂(2.5%、5%、7.5%)、三種飛灰中CaO含量(3.37%、5%、10%)及四種不同SS/SH比例(0、0.5、1、1.5)等配比因子，對鹼激發無機聚合物漿體凝結時間與硬固性質之影響。
研究結果顯示：(1)矽酸鈉溶液模數為1.5、2、2.5時，無機聚合物漿體初凝時間依序為93.3、75.7、48分鐘；矽酸鈉溶液與氫氧化鈉溶液重量比為0、0.5、1及1.5時，無機聚合物漿體初凝時間依序為105、90、85及78分鐘，增加此兩種配比因子均會縮短凝結時間。(2)硼砂比率為2.5%、5%、7.5%時漿體初凝時間依序為149.3、291、382.3分鐘，具有明顯緩凝效果，平均每添加1%硼砂可延長 44.518%凝結時間；CaO含量為3.37%、5%、10%時，漿體初凝時間依序為74.5、59.9、25分鐘具有明顯速凝效果，平均每添加飛灰總重1%之CaO會使凝結時間加速10.73%。(3) 25天齡期鹼激發無機聚合物漿體長度變化量為-0.001%至-0.790%，以水玻璃模數對於漿體長度變化量影響最大，當液固比為0.45及水玻璃模數1.5與2.5之漿體長度變化量分別為膨脹0.0063%與收縮0.79%，差值可達到0.7963%。(4)齡期28天鹼激發無機聚合物抗壓強度範圍為21.51 MPa至102.78 MPa，水玻璃模數影響最大，當液固比為0.45及水玻璃模數為1.5與2.5時之漿體抗壓強度分別為21.51 MPa及78.04 MPa，相差達371%。

This study explored the effects of proportional factors of three liquid-solid ratios (0.45, 0.5, 0.55), three modula of sodium silicate solution (water glass) (1.5, 2.0, 2.5), three borax content (2.5%, 5%, 7.5%) and three CaO content in fly ash (3.37%, 5%, 10%) and four different SS/SH ratios (0, 0.5, 1, 1.5) on the setting time and hardening properties of alkali-activated geopolymer paste.
The research results show that: (1) When the modula of sodium silicate solution were 1.5, 2 and 2.5, the initial setting times of alkali-activated geopolymer paste were 93.3, 75.7 and 48 minutes in sequence; and became 105, 90, 85 and 78 minutes in sequence when the weight ratios of sodium silicate solution to sodium hydroxide solution were 0, 0.5, 1 and 1.5. Increasing these two proportioning factors will shorten the setting time. (2) When the borax ratios were 2.5%, 5% and 7.5%, the initial setting times of alkali-activated geopolymer paste were 149.3, 291 and 382.3 minutes in sequence to showapparenteffect, in which the average setting time can extend by 44.518%per 1% addition of borax; When the CaO contents were 3.37%, 5% and 10%, the initial setting time of alkali-activated geopolymer paste were 74.5, 59.9 and 25 minutes in sequence. The average setting time will be accelerated by 10.73% per 1% addition of CaO of total weight of fly ash. (3) The shrinkage of alkali-activated geopolymer laste at age of 25 days were -0.001% to -0.790%. The modulus of water glass has the greatest influence on the shrinkage. When the liquid-solid ratio was 0.45, the shrinkage of of paster with modula of water glass of 1.5 and 2.5 were 0.0063% in expansion and 0.79% in shrinkage, respectively, to have the difference by 0.7963%. (4) The compressive strengths of hardened alkali-activated geopolymer paste at age 28 days were between 21.51 MPa and 102.78 MPa, in which the grestedt influence belonged to the water glass modulus. When the liquid-solid ratio was 0.45 and the modula of water glass were 1.5 and 2.5, the compressive strength of were 21.51 MPa and 78.04 MPa, respectively, with a big difference of 371%.
