Zusammenfassung:	To provide a simultaneously-adding-type additive for a hydraulic composition that, in a high temperature environment, exhibits effects such as slump retention that are comparable to those in normal environments, and can retain excellent flowability.SOLUTION: An additive for a hydraulic composition has A component, B component, C component, and D component. When the total content of A component, B component, C component, and D component is 100 mass%, the content of A component is 5-65 mass%, the content of B component is 15-75 mass%, the content of C component is 10-70 mass%, and the content of D component is 10-70 mass%.SELECTED DRAWING: None 【課題】高温環境下であっても標準環境と同等のスランプ保持性等の効果を発揮し、良好な流動性を保持することの可能な同時添加型の水硬性組成物用添加剤を提供する。【解決手段】水硬性組成物用添加剤は、Ａ成分と、Ｂ成分と、Ｃ成分と、Ｄ成分とを含有し、Ａ成分、Ｂ成分、Ｃ成分、及びＤ成分の含有割合の合計を１００質量％とした場合において、Ａ成分を５〜６５質量％、Ｂ成分を１５〜７５質量％、Ｃ成分を１０〜７０質量％、及びＤ成分を１０〜７０質量％の割合でそれぞれ含有する。【選択図】なし
