ACCELERATING AGENT FOR CEMENT, ULTRA RAPID HARDENING POWER ADMIXTURE FOR SPRAY MATERIAL AND SPRAY MATERIAL
PROBLEM TO BE SOLVED: To provide an accelerating agent for cement for obtaining an admixture for spray material with which curing together with high strength development proceeds extremely quickly, and an ultra rapid hardening power admixture using the same.SOLUTION: An accelerating agent for cement contains CaO-AlO-SiO-FeO-based amorphous material having content molar ratio (CaO/AlO) of CaO to AlOas chemical components of 2.0 to 2.6, contains the CaO and AlOof 86 to 94 mass% as total and the balance containing SiOand FeOas chemical components with content mass ratio (SiO/FeO) of 8 to 15 and percentage content of SiOand FeOin the balance of 50 mass% or more.SELECTED DRAWING: None
【課題】 高い強度発現を伴う硬化が格段に早く進む吹付材用の混和材を得るためのセメント用急結剤とこれを用いた超速硬粉体混和材を提供する。【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８６〜９４質量％含み、残部に化学成分としてのＳｉＯ2とＦｅ2Ｏ3を含有質量比（ＳｉＯ2／Ｆｅ2Ｏ3）８〜１５で含み、残部中の前記ＳｉＯ2とＦｅ2Ｏ3の含有割合が５０質量％以上であるＣａＯ−Ａｌ2Ｏ3−ＳｉＯ2−Ｆｅ2Ｏ3系非晶質物質を有効成分とするセメント用急結剤。【選択図】 なし
