CEMENT ADMIXTURE, EXPANSION MATERIAL, AND CEMENT COMPOSITION
To provide a cement admixture capable of: imparting a large expansion to a concrete from after the concrete is placed until an initial material age, e.g., 2-7 days of a material age; preventing warps due to dry shrinkage; and inhibiting the degradation of long-time strength developability.SOLUTION: A cement admixture contains a free lime and a hydraulic compound, and includes SrO as a chemical component.SELECTED DRAWING: None
【課題】コンクリート打設後の初期材齢（例えば、材齢２日〜７日）にかけてコンクリートに大きな膨張を付与し、乾燥収縮ひずみを抑制し、長期強度発現性の低下を抑えることが可能なセメント混和材を提供する。【解決手段】遊離石灰、水硬性化合物を含有し、化学成分としてＳｒＯを含むセメント混和材である。【選択図】なし
