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.
