HYDRAULIC COMPOSITION, HYDRAULIC MORTAR AND HARDENED BODY THEREOF
PROBLEM TO BE SOLVED: To provide a hydraulic composition capable obtaining a hardened body having excellent shrinkage reduction effect even in a high-temperature environment and capable of having a proper amount of air and maintaining good freeze-thaw resistance.SOLUTION: There is provided a hydraulic composition which comprises an alkylene oxide adduct represented by the general formula (1) and in which the cloud point of a 1 mass% aqueous solution of the alkylene oxide adduct is 18 to 72°C. RO-[(PO)/(EO)]-H (1) (where, R represents an alkyl group having 18 or more carbon atoms or alkenyl group; the alkyl group or the alkenyl group in R is a linear or branched; PO represents an oxypropylene group, EO represents an oxyethylene group: and p and q satisfy the following formulas (A) to (C): 1≤p≤20 (A), 1≤q≤30 (B) and 10
【課題】 高温環境下においても優れた収縮低減効果を有し、且つ、適度な空気量を有し良好な凍結融解抵抗性を維持できる硬化体を得ることが可能な、水硬性組成物を提供すること。【解決手段】 下記一般式（１）で表される第１のアルキレンオキサイド付加物を含み、上記第１のアルキレンオキサイド付加物の１質量％水溶液の曇点が１８〜７２℃である、水硬性組成物。ＲＯ−［（ＰＯ）ｐ／（ＥＯ）ｑ］−Ｈ （１）（式（１）中、Ｒは炭素数１８以上のアルキル基又はアルケニル基を示し、Ｒ中のアルキル基又はアルケニル基は直鎖状又は分枝鎖状であり、ＰＯはオキシプロピレン基、ＥＯはオキシエチレン基を示し、ｐ及びｑは下記式（Ａ）〜（Ｃ）を満たす。）１≦ｐ≦２０ （Ａ）１≦ｑ≦３０ （Ｂ）１０＜ｐ＋ｑ≦３０ （Ｃ）【選択図】図１
