QUICK-HARDENING ADMIXTURE AND QUICK-HARDENING CEMENT COMPOSITION
To provide a quick-hardening admixture that can express strength in a short time and can prevent the penetration of a degradation factor, and a quick-hardening cement composition.SOLUTION: A quick-hardening admixture contains a cement admixture containing at least one non-hydraulic compound selected from the group consisting of γ-2CaO SiO2, 3CaO 2SiO2, α-CaO SiO2, and calcium magnesium silicate, where the non-hydraulic compound contains Li, the content of the Li being 0.001-1.0 mass% in terms of oxide, a calcium aluminate and a gypsum.SELECTED DRAWING: None
【課題】短期強度の発現と劣化因子の浸透を抑制し得る急硬性混和材および急硬性セメント組成物を提供すること。【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１種又は２種以上の非水硬性化合物を含むセメント混和材であって、前記非水硬性化合物中にＬｉを含有し、該Ｌｉの含有率が酸化物換算で０．００１～１．０質量％であるセメント混和材とカルシウムアルミネート類とセッコウ類とを含有してなる急硬性混和材である。【選択図】なし
