Cement admixture, method for producing cement admixture, and cement composition
A cement admixture containing a dicalcium silicate compound having an average particle diameter as measured by microscopic observation of 5-100 [mu] m and an average aspect ratio represented by (major axis diameter/minor axis diameter) of 1.3 or more. According to the present invention, a cement admixture having excellent fire resistance, excellent compressive strength residual ratio and Young's modulus residual ratio after heating, and excellent neutralization resistance after heating can be provided.
含有通过显微镜观察测定的平均粒径为5～100μm、并且由(长轴径/短轴径)表示的平均纵横比为1.3以上的硅酸二钙化合物而成的水泥外加剂。能够提供耐火性优异并且受热后的压缩强度残存比和杨氏模量残存比、以及受热后的中性化抵抗性优异的水泥外加剂。
