摘要(中)

本研究以CFB副產石灰20%、30%和40%掺合水淬爐石粉進行激發作用，並添加4%和8%含鹼量與0.6、0.9和1.2模數比之鹼激發劑，量測不同齡期抗壓強度、膨脹、乾縮、流度與凝結時間等特性，配合XRD射線繞射分析和熱重分析(TGA)進行微觀觀測。研究結果顯示，當CFB副產石灰摻配比例為30%時，添加適量之鹼激發劑可以有效改善其強度發展並抑制膨脹反應。微觀分析亦發現：CFB副產石灰摻用比例達30%及40%時有大量鈣礬石產出和氫氧化鈣轉移，會造成膨脹量增加和抗壓強度降低，而添加適當含鹼量和模數比則能夠抑制膨脹量、減少鈣礬石和提升抗壓強度。

摘要(英)

This study focused on the production of activated reaction using 20%, 30%, 40% CFB ash and ground granulated blast furnace slag (GGBFS) with 4%, 8% Na2O content and 0.6, 0.9, 1.2 M.S.(modulus of water-glass). The research observed it is mechanical strength, expansion, shrinkage and workability. And use precision Instruments analysis such as XRD and TGA to verify the conclusion. The results indicate for 70% GGBFS-30% CFB ash, the addition of proper alkali activators improve the strength development and expansion behavior. Microscopic detection shows that added 30 % and 40 % CFB producing large amount of ettringite and Ca(OH)2, which will cause high expansion and low mechanical strength. And add an appropriate amount of alkali activate slag with suitable Ms that could control expansion.
