Title:
GROUT MATERIAL AND METHOD FOR INJECTING
Document Type and Number:
Japanese Patent JP3845629
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To propose a means for using electrolyte ionic water as mixed water and to provide a low-viscosity grout material having good fluidity and excellent pressure-sensitive adhesion and scarcely causing bleeding even in the absence of fresh-water.
SOLUTION: The grout material is used for injecting and filling cavities in the ground or cavities present in the boundary surface of the ground and a structure. The grout material is composed by mixing cement with an acidic aluminum salt and water containing the electrolyte ions. The method for injecting the grout is carried out as follows. Both a mixture liquid of the cement with the water containing electrolyte ions as a liquid A and an acidic aluminum salt solution as a liquid B are joined and mixed at an injection tip and then injected. The grout material has characteristics of the low viscosity, good fluidity and excellent pressure-sensitive adhesion though the bleeding is scarcely caused.
