    Abstract: 循環式流體化床鍋爐(Circulating Fluidized Bed Boiler,簡稱 CFB),以
    放,故混合石灰石進行脫硫,其製程所產生之工業副產物,即為 CFB 副
    本研究係添加三種不同強塑劑於 CFB 副產石灰-水淬爐石-水泥粉系統
    研究結果顯示,於水泥漿試驗中添加三種不同強塑劑於 CFB 副產石
    最好,劑量在 0.55%時即達到飽和效果。後續添加高分子聚合羧酸 0.55%
    於砂漿與混凝土進行試驗,試驗結果顯示 CFB 副產石灰-水淬爐石粉系統
    添加高分子聚合羧酸能有效提升工作性,其工作性趨近於 OPC 組。添加
    ;Circulating Fluidized Bed (CFB) Boiler is a means of energygenerating
    process by burning petroleum coke. In order to avoid blazed petroleum coke with
    high sulfur content from emitting overdosed sulfur dioxide, limestone is
    introduced in the boiler for desulfuration. The residue collected from the boiler is
    called CFB Byproduct Lime.
    In this study, three different superplasticizers added to CFB byproduct lime
    - granulated blast furnace slag system, the proposed a technique to find the
    optimal dosage of superplasticizer with the flowing-slump and mini-slump test.
    Follow-up applied to mortar and concrete, in order to understand the
    superplasticizer for this system can provide workability. Furthermore, in order to
    improve the problem of setting time, the introduction of an alkaline-activated
    systems to such systems.
    The results show a superplasticizer added three different paste test in CFB
    byproduct lime - granulated blast furnace slag system can effectively enhance the
    work of, according to the composition of each superplasticizer a different
    saturation point of this system are not the same. Three superplasticizer plasticizers
    to the polycarboxyic acid sodium salt by the work of the best acid dose when
    0.55% is reached saturation effect. Adding subsequent high polymer acid 0.55%
    in mortar and concrete test, the test results show CFB byproduct lime - granulated
    blast furnace slag acid polymer powder added to the system can effectively
    enhance the work of its working group of close to OPC.
