HYDRAULIC COMPOSITION, MANUFACTURING METHOD OF HYDRAULIC HARDENED BODY, AND HYDRAULIC COMPOSITION HARDENED BODY
To provide a hydraulic composition which on manufacture of a hydraulic composition hardened body, has good retention time of flowability, produces a hardened body exhibiting compression strength that allows demolding in a short period of time and exhibiting sufficient strength thereafter by passage of time, a manufacturing method of a hydraulic composition hardened body, and a hydraulic composition hardened body which is a hardened body of the hydraulic composition.SOLUTION: Disclosed is a hydraulic composition and an application thereof, wherein the hydraulic composition contains a hydraulic binder A, water B, a chemical admixture C for a hydraulic composition that is a vinyl copolymer including a constitutional unit 1 having an oxyalkylene group in its side chain and a constitutional unit 2 such as acrylic acid, and a hardening accelerator D for a hydraulic composition, containing an inorganic sulfate, calcium sulfoaluminate, and an inorganic hydroxide at a predetermined ratio, the hardening accelerator D for a hydraulic composition including 2-10 pts.mass with respect to 100 pts.mass of the hydraulic binder A.SELECTED DRAWING: None
【課題】水硬性組成物硬化体の製造に際し、流動性の保持時間が良好であり、短時間で脱型可能な圧縮強度が発現され、その後、経時により充分な強度が発現される硬化体が得られる水硬性組成物、水硬性組成物硬化体の製造方法及び該水硬性組成物の硬化物である水硬性組成物硬化体を提供する。【解決手段】水硬性結合材Ａ、水Ｂ、側鎖にオキシアルキレン基を有する構成単位１とアクリル酸等の構成単位２とを含むビニル共重合体である水硬性組成物用混和剤Ｃ、及び、無機硫酸塩と、カルシウムサルフォアルミネートと、無機水酸化物とを所定の比率で含む水硬性組成物用硬化促進材Ｄを含有する水硬性組成物であり、水硬性組成物用硬化促進材Ｄを、水硬性結合材Ａ１００質量部に対して２質量部～１０質量部含有する水硬性組成物及びその応用。【選択図】なし
