Title:
繊維入りセメントミルクおよび繊維入りセメントミルクの圧送ポンプによる注入方法
Document Type and Number:
Japanese Patent JP7228416
Kind Code:
B2
Abstract:
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
