CEMENT ADMIXTURE, CEMENT ADMIXTURE MANUFACTURING METHOD, AND CEMENT COMPOSITION
To provide a cement admixture that has excellent fire resistance and has excellent residual ratios of compressive strength and Young's modulus after heat receiving, as well as excellent neutralization resistance after heat receiving.SOLUTION: A cement admixture of the invention contains a dicalcium silicate compound having an average particle size of 5 to 100 μm as measured by microscopic observation and an average aspect ratio expressed as (major axis diameter/minor axis diameter) of 1.3 or greater.SELECTED DRAWING: None
【課題】耐火性に優れ、かつ、受熱後の圧縮強度残存比とヤング係数残存比、また、受熱後の中性化抵抗性に優れたセメント混和材を提供すること。【解決手段】顕微鏡観察により測定される平均粒子径が５～１００μｍであり、かつ、（長軸径／短軸径）で表される平均アスペクト比が１．３以上であるダイカルシウムシリケート化合物を含有してなるセメント混和材である。【選択図】なし
