GROUT MORTAR COMPOSITION, GROUT MORTAR, CONCRETE STRUCTURE, AND PRODUCTION METHOD FOR THE SAME
To provide a grout mortar composition excellent in quick hardening and strength development while keeping appropriate fluidity.SOLUTION: A grout mortar composition of this invention includes a binder consisting of cement, calcium aluminate and gypsum, fine aggregate, a defoamant, and a thickener, in which a sum of the contents of the defoamant and the thickener is 0.03-1.0 pt.mass relative to 100 pts.mass of the binder, and a mass ratio of the defoamant to the thickener (mass of defoamant/mass of thickner) is 0.5-9.SELECTED DRAWING: None
【課題】適度な流動性を保持しつつ、速硬性且つ強度発現性に優れるグラウトモルタル組成物を提供すること。【解決手段】セメント、カルシウムアルミネート類及び石膏類からなる結合材と、細骨材と、消泡剤と、増粘剤とを含み、消泡剤及び増粘剤の合計含有量が、結合材１００質量部に対し、０．０３〜１．０質量部であり、増粘剤に対する消泡剤の質量比（［消泡剤の質量］／［増粘剤の質量］）が、０．５〜９である、グラウトモルタル組成物。【選択図】なし
