More Information
Summary:To provide a post-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 X component, Y component, and Z component. When the total content of X component, Y component, and Z component is 100 mass%, the content of X component is 20-80 mass%, the content of Y component is 10-70 mass%, and the content of Z 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後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、Ｘ成分と、Ｙ成分と、Ｚ成分とを含有し、Ｘ成分、Ｙ成分、及びＺ成分の含有割合の合計を１００質量％とした場合において、Ｘ成分を２０〜８０質量％、Ｙ成分を１０〜７０質量％、及びＺ成分を１０〜７０質量％の割合でそれぞれ含有する。【選択図】なし
