SELECTION METHOD OF BLAST FURNACE SLAG, AND MANUFACTURING METHOD OF BLAST FURNACE CEMENT
PROBLEM TO BE SOLVED: To provide a selection method of a blast furnace slag and a manufacturing method of a blast furnace cement that can accurately predict an activity index of cement and can select a blast furnace slag as a cement material having a high activity index.SOLUTION: The selection method of a blast furnace slag includes an indicator calculation process and a selection process. In the indicator calculation process, a basicity Bu (seven days) of the blast furnace slag as an indicator of the activity index of the cement of mortar material age of seven days is calculated using the following equation (1) Bu(seven days)=(CaO+a×MgO+b×AlO)/SiO-c×TiO-d×MnO...(1). In the equation (1), a is 0.05-0.65, b is 0.05-0.95, c is 0.15-2.00, and d is 0.05-0.95. In the selection process, a blast furnace slag is selected on the basis on the basicity Bu (seven days) as the indicator.SELECTED DRAWING: Figure 1
【課題】セメントの活性度指数を精度よく予測することができ、優れた活性度指数を有するセメント原料としての高炉スラグを選別することができる高炉スラグの選別方法及び高炉セメントの製造方法を提供する。【解決手段】モルタル材齢７日のセメントの活性度指数の指標となる高炉スラグの塩基度Ｂｕ（７日）を下記式（１）Ｂｕ（７日）＝（ＣａＯ＋ａ×ＭｇＯ＋ｂ×Ａｌ２Ｏ３）／ＳｉＯ２−ｃ×ＴｉＯ２−ｄ×ＭｎＯ・・・（１）（但し、式（１）中、ａは０．０５〜０．６５、ｂは０．０５〜０．９５、ｃは０．１５〜２．００、ｄは０．０５〜０．９５である。）により算出する指標算出工程と、指標となる塩基度Ｂｕ（７日）に基づいて高炉スラグを選別する選別工程を含むことを特徴とする高炉スラグの選別方法である。【選択図】図１
