QUICK SETTING SUBSTANCE AND QUICK SETTING MATERIAL FOR CEMENT COMPOSITION
PROBLEM TO BE SOLVED: To provide a calcium aluminate-based quick setting substance which can sufficiently develop high quick setting property and is remarkably excellent in cost performance and quick setting property, without using a sintering aid together in an increased amount, and a quick setting material for cement composition using the same.SOLUTION: A quick setting substance is provided that is formed from a CaO-AlO-SiO-KO-based amorphous body in which: a content molar ratio (CaO/AlO) of CaO and AlOas chemical components is 2.0-2.6; 90-94 mass% of CaO and AlOis contained in total; a content mass ratio (SiO/KO) of silicon and potassium in terms of an oxide is 24.3-34.3; and 4-5 mass% of the total of SiOand KO in terms of the oxide is contained.SELECTED DRAWING: None
【課題】 急結助剤類の増量併用を行わなくても、高い急結性を十分発現させることのできる、コストパフォーマンスと急結性に格段に優れたカルシウムアルミネート系の急結性物質とこれを用いたセメント組成物用急結材を提供する。【解決手段】 化学成分としてのＣａＯとＡｌ2Ｏ3の含有モル比（ＣａＯ／Ａｌ2Ｏ3）が２．０〜２．６であって、前記ＣａＯとＡｌ2Ｏ3を合計で９０ 〜９４質量％含み、かつ珪素とカリウムを酸化物換算した含有質量比（ＳｉＯ2／Ｋ2Ｏ）が２４．３〜３４．３であって、前記酸化物換算したＳｉＯ2とＫ2Ｏを合計で４〜５質量％含むＣａＯ−Ａｌ2Ｏ3−ＳｉＯ2−Ｋ2Ｏ系非晶質体からなる急結性物質。【選択図】 なし
