HYDRAULIC COMPOSITION AND CONCRETE
To provide a hydraulic composition having high early strength development while securing workability, and concrete using the same.SOLUTION: The hydraulic composition comprises a binder containing hydraulic cement, a hardening accelerator containing calcium nitrite and calcium nitrate, and a chemical admixture, with the total mass of calcium nitrite and calcium nitrate in the hardening accelerator being 0.3 to 2.0 mass parts relative to 100 mass parts of the binder, and the mass ratio of calcium nitrite and calcium nitrate (calcium nitrite/calcium nitrate) in the hardening accelerator being 0.1 to 1.0.SELECTED DRAWING: None
【課題】作業性を確保しながら、早期強度発現性の高い水硬性組成物及びそれを用いたコンクリートを提供するものである。【解決手段】水硬性セメントを含む結合材、亜硝酸カルシウム及び硝酸カルシウムを含む硬化促進剤、化学混和剤を含む水硬性組成物であって、前記硬化促進剤中の亜硝酸カルシウム及び硝酸カルシウムの合計質量が前記結合材１００質量部に対し、０．３〜２．０質量部であり、かつ前記硬化促進剤中の亜硝酸カルシウムと硝酸カルシウムの質量比（亜硝酸カルシウム／硝酸カルシウム）が０．１〜１．０である水硬性組成物。【選択図】なし
