CEMENT COMPOSITION AND METHOD OF PRODUCING CEMENT COMPOSITION
PROBLEM TO BE SOLVED: To provide a cement composition high in shrinkage reducing performance and initial strength development.SOLUTION: A cement composition has CS of 45-75 mass%, CS of 5-30 mass%, CA of 5-15 mass%, and CAF of 5-15 mass%, calculated by Bogue equations; a Li content of 0.01 mass%-0.1 mass% (excluding the Li content of 0.01 mass%); and a CS-M1 phase ratio of 0.4 or more.
【課題】高い収縮低減性能及び初期強度発現性を有するセメント組成物を提供する。【解決手段】ボーグ式で算出されるＣ３Ｓが４５〜７５質量％、Ｃ２Ｓが５〜３０質量％、Ｃ３Ａが５〜１５質量％、及びＣ４ＡＦが５〜１５質量％であり、Ｌｉ含有量が０．０１質量％〜０．１質量％（但し、Ｌｉ含有量が０．０１質量％を除く）であり、Ｃ３Ｓ−Ｍ１相比率が０．４以上であるセメント組成物。【選択図】なし
