BLAST FURNACE SLAG FINE PARTICLE COMPOSITION AND CEMENT COMPOSITION CONTAINING THE BLAST FURNACE SLAG FINE PARTICLE COMPOSITION
PROBLEM TO BE SOLVED: To provide a blast furnace slag fine particle composition and a cement composition containing the blast furnace slag fine particle composition capable of resolving two problems that 1) compressive strength of initial material age and middle and long term material age is low and 2) a hydration reaction of the blast slag is decelerated and especially compressive strength of the middle and long term material age is reduced when it received high temperature history by hydration heat.SOLUTION: There is used a blast furnace slag fine particle composition obtained by adding an additive composition containing following 3 components of A to C, specific water soluble dextrin as an A component, specific polyalkylene glycol monoalkyl ether as a B component and one or two selected from ethylene glycol, diethylene glycol and glycerine as a C component at a specific ratio in a pulverization process of a blast slag and mixing and powdering.SELECTED DRAWING: None
【課題】高炉スラグを多く含有するコンクリートは、１）初期材齢及び中長期材齢の圧縮強度が低いこと、２）水和熱により高温履歴を受けると高炉スラグの水和反応が鈍化し特に中長期材齢の圧縮強度が低下すること、以上の２つの課題を同時に解決することができる高炉スラグ微粉末組成物及び該高炉スラグ微粉末組成物を含有するセメント組成物を提供する。【解決手段】Ａ成分として特定の水溶性デキストリン、Ｂ成分として特定のポリアルキレングリコールモノアルキルエーテル、Ｃ成分としてエチレングリコール、ジエチレングリコール及びグリセリンの中から選ばれる一つ又は二つ、以上のＡ〜Ｃの３成分を特定割合で含有する添加剤組成物を高炉スラグの微粉砕工程で添加し混合粉砕して得られる高炉スラグ微粉末組成物を用いることを特徴とする。【選択図】なし
