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 0.16 ≤ n/(p+n+m) ≤ 0.40, and a second requirement, which is 20 ≤ (p+n+m) ≤ 48. General formula (1): RO-(AO)p-(EO)n-(AO)m...

More Information
Summary: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 0.16 ≤ n/(p+n+m) ≤ 0.40, and a second requirement, which is 20 ≤ (p+n+m) ≤ 48. General formula (1): RO-(AO)p-(EO)n-(AO)m-H (wherein R represents a C8-30 alkyl or alkenyl group and has a linear or branched structure; the AO moieties are the same or different, C3-18 oxyalkylene groups; EO represents an oxyethylene group; and p, n, and m, each indicating the average number of moles added, are 0 or larger, 1 or larger, and 1 or larger, respectively.).
