BLAST FURNACE SLAG FINE POWDER AND MANUFACTURING METHOD THEREOF
To provide a blast furnace slag fine powder having a large activity index even though having a low basicity (specifically, 1.40 to 1.70) and a Blaine specific surface area which is not excessively large (specifically, 3,000 to 5,500 cm2/g) and capable of being suitably used as a cement admixture.SOLUTION: A blast furnace slag fine powder has a 5% volume cumulative particle diameter of 1.60 μm or less, a 10% volume cumulative particle diameter of 2.20 μm or less, a Blaine specific surface area of 3,000 to 5,500 cm2/g, and a basicity of 1.40 to 1.70 defined as "JIS A 6206:2013 (ground granulated blast furnace slag for concrete)".SELECTED DRAWING: None
【課題】塩基度が低く（具体的には、１．４０～１．７０）、かつ、ブレーン比表面積が過度に大きくない（具体的には、３，０００～５，５００ｃｍ２／ｇ）にもかかわらず、活性度指数が大きく、セメント混合材として好適に使用することができる高炉スラグ微粉末を提供する。【解決手段】５％体積累積粒径が１．６０μｍ以下、１０％体積累積粒径が２．２０μｍ以下、ブレーン比表面積が３，０００～５，５００ｃｍ２／ｇ、及び「ＪＩＳ Ａ ６２０６：２０１３（コンクリート用高炉スラグ微粉末）」に規定される塩基度が１．４０～１．７０である高炉スラグ微粉末。【選択図】なし
