The inorganic powder composite includes: an inorganic powder; and a first hydrophobic treatment agent, a second hydrophobic treatment agent, and a hydrophilic treatment agent, which cover at least one part of a surface of the inorganic powder, the first hydrophobic treatment agent is a silicon compound, the second hydrophobic treatment agent is a fatty acid, and the hydrophilic treatment agent is hydrous silica.

Abstract: A suspension-type grouting liquid for injection into a ground includes sodium aluminate having a mol ratio of 10 or more; and slag, wherein the mol ratio of sodium aluminate is defined as molar concentration of Na.sub.2 O/molar concentration of Al.sub.2 O.sub.3. Preferably, the slag is fine grained and has a specific surface area of 8000 cm.sup.2 /g or more. The grouting liquid may further include at least one additional material selected from the group consisting of cement and dispersant. Preferably the cement is fine grained and has a specific surface area of 8000 cm.sup.2 /g or more. The grouting liquid shows high strength of consolidation in use in spite of having a low viscosity and a long gelation time, and shows a long duration of the strength of consolidation. Another embodiment of the grouting liquid includes water glass having a mol ratio of 2.5 or less; and slag, wherein the mol ratio of the water glass is defined as molar concentration of SiO.sub.2 /molar concentration of Na.sub.

Abstract: A suspension-type grouting liquid for injection into a ground having excellent penetration properties, e.g. low viscosity and long gelation time, and having comparatively high strength after consolidation. The suspension-type grouting liquid for injection into a ground consists essentially of slag, or a combination of slag and cement, alkali metal aluminates, and water. The slag is a fine grain having specific surface area of 5000 cm.sup.2 /g or more, and the alkali metal aluminates have a mole ratio of ({Me.sub.2 O}/{Al.sub.2 O.sub.3 }) of 2.8 or more, in which Me means alkali metal, {Me.sub.2 } and {Al.sub.2 O.sub.3 } represent, respectively, molar concentration of Me.sub.2, and Al.sub.2 O.sub.3.

Abstract: An injection process for solidifying a soft ground by injecting a blend of water glass type grout thereinto which is a non-alkaline aqueous solution of silicic acid obtained by the mixing water glass into an aqueous solution of acidic reactant so as to remove alkali from the water glass, and an injection apparatus for practicing the injection process which comprises a mixing container for preparing the non-alkaline aqueous solution of silicic acid by adding and mixing the water glass into the aqueous solution of acidic reactant.
