HYDRAULIC COMPOSITION ADDITIVE
To provide a hydraulic composition additive capable of improving early-strength of a cured body of a hydraulic composition, for example, high-early strength developed approximately after 17 hours.SOLUTION: The hydraulic composition additive comprises at least one chemical compound selected from chemical compounds represented by the following chemical formula (A1) and a chemical compound represented by the following chemical formula (A2), provided that M1 to M3 each independently represent a counter ion, R1 to R9 are each hydrogen or a hydroxy group, one or more and two or less of R1 to R5 is a hydroxy group, R4 is a hydroxy group when R1 is a hydroxy group, R2 is a hydroxy group when R5 is a hydroxy group, and at least one of R6 to R9 is a hydroxy group, in the chemical formulae.SELECTED DRAWING: None
【課題】水硬性組成物の硬化体の早強性、例えば１７時間程度の早強性を向上できる水硬性組成物用添加剤を提供する。【解決手段】下記の化学式（Ａ１）で表される化合物及び化学式（Ａ２）で表される化合物から選択される１種以上の化合物を含む、水硬性組成物用添加剤である。【化１】JPEG2022045007000009.jpg38160〔Ｍ１～Ｍ３は、それぞれ独立に、対イオンを示す。Ｒ１～Ｒ９は、水素もしくは水酸基である。Ｒ１～Ｒ５は、そのうち１つ以上２つ以下は水酸基である。Ｒ１が水酸基の場合Ｒ４も水酸基であり、Ｒ５が水酸基の場合Ｒ２も水酸基である。Ｒ６～Ｒ９のうち１つ以上は水酸基である。〕【選択図】なし
