SALINITY TOLERANCE GROUT COMPOSITION AND SALINITY TOLERANCE GROUT
To provide a salinity tolerance grout composition and a salinity tolerance grout which are excellent in fluidity and material separation resistance, and excellent also in strength development and salinity tolerance.SOLUTION: A salinity tolerance grout composition comprises: a binder made of a cement; an amorphous aluminosilicate and a blast furnace slag; a water reducing agent containing a naphthalene sulfonic acid reducing agent; an expander; and a fine aggregate, in which, relative to 100 pts.mass of the binder, the content of the blast furnace slag is 2 to 45 pts.mass, the content of the naphthalene sulfonic acid reducing agent is 0.55 to 1.5 pts.mass.SELECTED DRAWING: None
【課題】流動性及び材料分離抵抗性に優れ、且つ強度発現性及び耐塩性にも優れる耐塩性グラウト組成物及び耐塩性グラウトを提供すること。【解決手段】セメント、非晶質アルミノシリケート及び高炉スラグからなる結合材と、ナフタレンスルホン酸系減水剤を含む減水剤と、膨張材と、細骨材とを含み、結合材１００質量部に対し、高炉スラグの含有量が２〜４５質量部であり、前記ナフタレンスルホン酸系減水剤の含有量が０．５５〜１．５質量部である、耐塩性グラウト組成物。【選択図】なし
