PURPOSE:To obtain an inorganic suspension type slurry for grout having stability for many hours and excellent permeability by subjecting a grout material consisting of a hydraulic inorganic substance having a specific particle size, dispersant and water to high-pressure dispersion treatment. CONSTITUTION:A suspension type slurry consisting of (A) a hydraulic inorganic substance (e.g. quenched blast furnace slag or the slag blended with gypsum, calcium hydroxide, sodium carbonate, aluminum nitrate, etc.) having <=5mum maximum particle diameter, (B) a dispersant and (C) water is prepared and the slurry is subjected to high-pressure dispersion treatment (300-400kg/cm<2>) to give the aimed slurry. |
