QUICK HARDENING ADDITIVE MATERIAL FOR CEMENT AND MANUFACTURING METHOD THEREFOR
PROBLEM TO BE SOLVED: To provide a quick hardening additive material for cement post-added to cement, excellent in hydration activity, exhibiting good quick hardening property as well as capable of sufficiently securing predetermined flowability even under low temperature and a manufacturing method therefor.SOLUTION: There is provided a quick hardening additive material for cement which is post-added to cement, contains C12A7-based mineral phase of 70 mass% or more, C3A of 5.0 mass% or less, Ti of 1.0 mass% or less in terms of TiO, Fe of 1.5 mass% or less in terms of FeOand has crystallite diameter of the C12A7-based mineral phase measured by an X ray diffraction of 150 to 500 nm and lattice constant of the C12A7-based mineral phase of 11.940 to 11.975Å and preferably further contains F of 0.5 to 3.0 mass%.SELECTED DRAWING: None
【課題】 低温においても、水和活性が優れて良好な急硬性能を示すと同時に所定の流動性を十分に確保することができる、セメントに後添加するセメント用急硬性添加材及びその製造方法を提供する。【解決手段】 セメント用急硬性添加材は、Ｃ１２Ａ７系鉱物相を７０質量％以上、Ｃ３Ａを５．０質量％以下、ＴｉをＴｉＯ２換算で１．０質量％以下、ＦｅをＦｅ２Ｏ３換算で１．５質量％以下含有し、Ｘ線回析で測定したＣ１２Ａ７系鉱物相の結晶子径が１５０〜５００ｎｍで、Ｃ１２Ａ７系鉱物相の格子定数が１１．９４０〜１１．９７５Åであり、好ましくはＦを０．５〜３．０質量％含有する。【選択図】 なし
