MIXED CEMENT AND COMPOSITION OF MIXED CEMENT
PROBLEM TO BE SOLVED: To provide a mixed cement and a composition of the mixed cement with a stable quality by reducing the amount of cement used and adding a blast furnace slag fine powder or the like.SOLUTION: There is provided a mixed cement having 30.5 to 34 pts.wt. of cement, 66 to 68 pts.wt. of a blast furnace slag fine powder to which gypsum is added and 0 to 1.5 pts.wt. of fly ash by mixing the cement, the blast furnace slag fine powder and the fly ash so that the total thereof is 100 pts.wt. to prepare a premix material. There is provided a mixed cement composition by mixing water, a fine aggregate and a coarse aggregate with the cement.SELECTED DRAWING: None
【課題】セメントの使用量を減らして、高炉スラグ微粉末等を加えた混合セメントについて、混合セメント、及び、混合セメントの組成物の品質の安定した供給の提供。【解決手段】３０．５〜３４重量部のセメントと、石膏を内添した６６〜６８重量部の高炉スラグ微粉末と、０〜１．５重量部のフライアッシュと、を有し、前記セメントと前記高炉スラグ微粉末と前記フライアッシュの合計が１００重量部となるように混合してプレミックス材とする混合セメント。前記セメントに水と細骨材と粗骨材とを混合した混合セメント組成物。【選択図】なし
