CEMENT MILK WITH FIBER
To provide cement milk with fiber having high fluidity, capable of being injected by a pressure pump, and used as a solidifying material liquid to be injected into soil in a ground improving construction method that builds an improved soil body by forcibly stirring and mixing, in the soil, the solidifying material liquid with in-situ soil.SOLUTION: The cement milk with fiber is produced in a form of slurry by blending cement or a cement-based solidifying material, a reinforcing fiber, basic magnesium carbonate, and water in a predetermined ratio. A polypropylene, nylon or vinylon fiber is blended as the reinforcing fiber. A water-cement ratio is in a range of 50% to 100%, and the basic magnesium carbonate is blended in a range of approximately 0.1 to 4.0% in terms of mass ratio to the cement.SELECTED DRAWING: Figure 1
【課題】流動性に富み、特に圧送ポンプによる注入が可能で、土中で原位置土と強制的に攪拌混合して改良体を造成する地盤改良工法などで、土中に注入される固化材液として用いられる繊維入りセメントミルクを提供する。【解決手段】セメントまたはセメント系固化材と補強用繊維と塩基性炭酸マグネシウムと水とを所定の割合で配合することによりスラリー状に製造する。補強用繊維としては、ポリプロピレン、ナイロンまたはビニロン繊維を配合する。水セメント比は50％〜100％の範囲、塩基性炭酸マグネシウムは、セメントに対する質量比で概ね0.1〜4.0％の範囲で配合する。【選択図】図１
