SURFACE AESTHETIC APPEARANCE IMPROVER FOR HYDRAULIC COMPOSITIONS
To provide a surface aesthetic appearance improver for a hydraulic composition that is capable of controlling the behavior of bubbles in the hydraulic composition, which causes bubble marks on a surface of a hardened body of the hydraulic composition, thereby improving the surface aesthetic appearance of the hardened body.SOLUTION: A surface aesthetic appearance improver for a hydraulic composition has a dynamic surface tension (σ1) of 55 mN/m or more at a bubble film life of 10 ms and a dynamic surface tension (σ2) of 35 mN/m or less at a bubble film life of 1,000 ms, as measured by a bubble pressure method (20°C).SELECTED DRAWING: None
【課題】水硬性組成物の硬化体表面の気泡痕の原因となる、水硬性組成物中の気泡の挙動を制御して、前記硬化体の表面美観を向上させることのできる、水硬性組成物用表面美観向上剤の提供。【解決手段】バブルプレッシャー法（２０℃）により測定したとき、泡膜寿命１０ｍｓにおける動的表面張力（σ１）が５５ｍＮ／ｍ以上であり、泡膜寿命１０００ｍｓにおける動的表面張力（σ２）が３５ｍＮ／ｍ以下である、水硬性組成物用表面美観向上剤。【選択図】なし
