SELF-SHRINKAGE REDUCING AGENT FOR CEMENT COMPOSITION AND CEMENT COMPOSITION
To provide a self-shrinkage reducing agent for a cement composition, which shows an excellent self-shrinkage reducing effect and further shows the self-shrinkage reducing effect with a small addition amount.SOLUTION: A self-shrinkage reducing agent for a cement composition comprises a divalent fatty acid metallic salt of a 2-10C fatty acid and a divalent metal. Preferably the divalent fatty acid metallic salt is a fatty acid magnesium. More preferably, a cement composition comprises 0.1-10.0 pts.mass of the self-shrinkage reducing agent based on 100 pts.mass of cement, and contains a dry-shrinkage reducing agent.SELECTED DRAWING: None
【課題】良好な自己収縮低減効果を発現するとともに、少ない添加量で自己収縮低減効果を発現するセメント組成物用自己収縮低減剤の提供。【解決手段】セメント組成物用自己収縮低減剤は、炭素数が２〜１０の脂肪酸と２価金属との２価脂肪酸金属塩からなる。好ましくは、２価脂肪酸金属塩が脂肪酸マグネシウムである。更に好ましくは、セメント１００質量部に対して、０．１〜１０．０質量部含有することが望ましく、乾燥収縮低減剤を含有することがさらに好ましい。【選択図】なし
