CEMENT ADMIXTURE, CEMENT ADMIXTURE MANUFACTURING METHOD, AND CEMENT COMPOSITION
To provide a cement admixture that can ensure initial strength even when a large amount of cement is substituted, and that can provide good strength developability through carbonation curing.SOLUTION: A Cement admixture of the invention contains: at least one non-hydraulic compound selected from the group consisting of γ-2CaO-SiO2, 3CaO-2SiO2, α-CaO-SiO2, and calcium magnesium silicate; and ye'elimite, wherein the content of ye'elimite is 0.1 to 10 mass%.SELECTED DRAWING: None
【課題】多量にセメントを置換しても初期強度を確保することができ、かつ炭酸塩(化)養生によって良好な強度発現性を付与できるセメント混和材を提供すること。【解決手段】γ－２ＣａＯ・ＳｉＯ２、３ＣａＯ・２ＳｉＯ２、α－ＣａＯ・ＳｉＯ２、及びカルシウムマグネシウムシリケートからなる群から選ばれる少なくとも１種の非水硬性化合物とイーリマイトを含むセメント混和材であって、イーリマイトの含有量が０．１～１０質量％であるセメント混和材である。【選択図】なし
