摘要(中)

本研究中探討兩項主題: (1) 卜作嵐材料對水泥漿試體內可溶性鹼含量影響及(2) 鋰化合物對卜作嵐水泥漿試體內的可溶性鹼含量影響，探討游離態鹼質於卜作嵐水泥漿試體內的變化行為，與添加鋰化合物於卜作嵐水泥漿中對游離態鹼質的影響。
結果顯示以爐石粉、飛灰取代部分水泥後，漿體有結合鹼質之行為，但當水泥的含鹼量較低時，飛灰及爐石粉釋出鹼質會增加試體內游離態鹼質的比例。由本研究的結果顯示，爐石粉、飛灰可以抑制混凝土ASR問題的機理，並非是導因於過去所認知的添加爐石粉或飛灰可以降低混凝土內的水溶性鹼的因素。
鋰化合物添加於爐石粉或飛灰水泥時，游離態鹼質的數量皆會隨著添加的Li/(Na+K)莫耳比增加而降低，Li+含量比例會隨著取代水泥量的增加而增加，顯示同時添加Li化合物及卜作嵐材料時，會產生更佳抑制ASR的效果。

摘要(英)

Two themes was explored in this study: (1) The effect of pozzolan material for water soluble alkali in slurry and (2) The effect of lithium compounds for water soluble alkali in portland-pozzolan slurry. To explore the changes behavior for free state alkali in portland-pozzolan slurry, and the effect for free state alkali of adding lithium compounds in
portland-pozzolan slurry.
The result showed that after slag and fly ash replaced part of cement, the slurry has a combining behavior, however, the use of low alkali cement. Fly ash and slag will increase the alkaline to release in the proportion of free-state alkali. The result shows that mechanism can inhibit problems of ASR by using slag and fly ash concrete, not cause the perception elements in the past that adds slag and fly ash can reduce the water-soluble alkali within the concrete.
When lithium compounds added to slag-cement or fly ash-cement, the number of free-state alkali will reduce as Li / (Na + K) molar ratio increased. Li + concentration ratio will increase with the replaced of the amount of cement. Display while adding Li compounds and pozzloan materials, will produce a better effect inhibition of ASR.
