BLAST FURNACE SLAG FINE POWDER AND CEMENT COMPOSITION
PROBLEM TO BE SOLVED: To provide a blast furnace slag fine powder that has unconventional physical properties and develops strength excellently, while it also has excellent flowability, prevents the contraction of its cured body, and has a high degree of powder fineness, and a cement composition prepared therewith.SOLUTION: A blast furnace slag fine powder has a particle size of 1.0-5.0 μm in the cumulative volume 50%, and a specific surface of 3.0 m/g or less by a BET multipoint method. More preferably, the blast furnace slag fine powder has a circularity of 0.950 or more in the cumulative number 50%.SELECTED DRAWING: None
【課題】従来にない物性を備え、強度発現性が良好でありながら、流動性にも優れ、硬化体の収縮の少ない微粉末度の高い高炉スラグ微粉末およびそれを用いたセメント系組成物の提供。【解決手段】高炉スラグ微粉末として、累積体積率５０％の粒子径が１．０〜５．０μｍであり、かつＢＥＴ多点法による比表面積が３．０ｍ２／ｇ以下である高炉スラグ微粉末。さらに好ましくは、高炉スラグ微粉末累積個数５０％の円形度が０．９５０以上である、高炉スラグ微粉末。【選択図】なし
