煉鋼副產品高爐爐渣為一優良卜作嵐材料，可取代部分水泥以製成
高爐水泥，也可當作鹼激發膠結材之原料，其抗壓強度數倍於波特蘭水
泥，但由於成本較高因而限制其應用。轉爐石亦為煉鋼副產品，其所含
玻璃體較少，因此卜作嵐活性偏低，並不適宜作為礦物掺料直接應用於
混凝土中。由於煉鋼過程中加入生石灰，導致轉爐石化學成份中含有游
離氧化鈣，易與水分反應，造成體積膨脹，目前再利用價值不高。
本研究將轉爐石部分取代爐石作為鹼激發膠結材原料，建立鹼激發
爐石-轉爐石之配比設計。本研究發現，使用氫氧化鈉與液態矽酸鈉混合
成鹼激發藥劑，所製成爐石膠結材試體28 天抗壓強度最高可達120MPa。
以粉狀矽酸鈉製成之爐石膠結材試體，28 天抗壓強度最高為102MPa，
其初凝時間最短為1 小時45 分鐘，且試體製作操作便利。此外，當選用
粉狀矽酸鈉作為鹼激發藥劑，AE=12%且轉爐石取代量20%時，砂漿28
天抗壓強度與流度分別為73MPa 及98%。因此，以轉爐石部分取代爐石
作為鹼激發膠結材原料，配合適當鹼激發藥劑，其砂漿抗壓強度及流動
性皆優於波特蘭水泥砂漿。若能以鹼激發爐石-轉爐石膠結材取代波特蘭
水泥，不僅能提高轉爐石再利用價值，同時也能減少水泥之用量，達到
節能減碳之目的。

Blast furnace slag is the by-product of steel manufacturing and is
typically used as a pozzolanic material. Slag can be utilized as a partial
replacement of Portland cement and as a raw material of alkali-activated
binders. As compared to Portland cement, the compressive strength of
alkali-activated slag is much higher; however, the cost of alkali-activated slag
is very expensive and thus limits its application in concrete. Less vitreous
BOF slag is also the by-product of steel manufacturing but has a lower
pozzolanic activity. Hence, BOF slag can not be directly used as a mineral
admixture in concrete. Lime added during the manufacturing of steel results
in the easy reaction of BOF slag with water and its volume expansion.
Consequently, the reuse of BOF slag is limited.
Here, BOF slag is used as a partial replacement of slag for the
production of alkali-activated slag binder. The mixture design for the
alkali-activated slag binder containing BOF slag is first investigated. It is
found that the 28-day compressive strength of alkali-activated slag binder
reaches 120MPa when the alkali activating solution of sodium hydroxide and
liquid sodium silicate is used. When easy mixing and production are sought,
the alkali activation solution containing powdered sodium silicate is used.
The 28-day compressive strength of the resulting alkali-activated slag binder
is reduced to 102MPa while its shortest initial setting time is 105 minutes.
In addition, the compressive strength and flow value of alkali-activated slag
binder are 73MPa and 98% respectively when powdered sodium silicate,
AE=12% and 20% slag replaced by BOF slag are used. Therefore, BOF slag
III
can be used as a raw material for the production of alkali-activated slag binder.
By mixing with adequate alkali activating solution, the resulting compressive
strength and flow value of alkali-activated slag mortars are superior to those
of Portland cement mortar. It is expected that energy conservation. carbon
reduction and reuse of BOF slag can be achieved if Portland cement is
completely replaced by alkali-activated slag binder containing BOF slag.
