ANTIFOAMING AGENT FOR HYDRAULIC COMPOSITION, ADDITIVE FOR HYDRAULIC COMPOSITION, AND HYDRAULIC COMPOSITION
An antifoaming agent for hydraulic compositions which is a polyoxyalkylene-based compound represented by general formula (1), the compound satisfying a first requirement, which is 0.02<=n/(n+m)<0.16,and a second requirement, which is 6<=(n+m)<=100. General formula (1): RO-[(EO)n/(AO)m]-H (wherein R represents a C8-30 alkyl or alkenyl group and has a linear or branched structure; EO represents anoxyethylene group; AO represents a C3-18 oxyalkylene group; n and m, each indicating the average number of moles added, are 1 or larger each; and [(EO)n/(AO)m] shows that n mole(s) of EO and m mole(s)of AO have been bonded by block addition or random addition.).
一种水硬性组合物用消泡剂，其为由下述通式(1)表示的聚氧化烯系化合物，并且满足以下关系：第1条件：0.02≦n/(n+m)＜0.16、以及第2条件：6≦n+m≦100。RO‑[(EO)n/(AO)m]‑H···(1)，其中，R表示碳原子数为8至30的烷基或烯基，且呈现直链或支链中的任一种结构。EO表示氧乙烯基，AO表示碳原子数为3至18的氧化烯基。n、m分别表示平均加成摩尔数，且n为1以上，m为1以上。此外，[(EO)n/(AO)m]表示n摩尔的EO与m摩尔的AO嵌段加成或者无规加成。
