<p>PROBLEM TO BE SOLVED: To obtain a ground consolidator which is injected into grounds such as soft grounds, etc., to consolidate grounds, exerts a long gelation time, a high permeability and a high consolidation strength, yields a consolidated body having a high durability and is highly safe against the environment, by allowing it to contain a dealkalized silica obtained by removing alkali from water glass and a cement or slaked lime as main components. SOLUTION: The subject ground consolidator comprises a dealkalized silica, obtained by removing a portion of or all sodium ions from water glass, and a cement as effective components and comprises slaked lime, slugs, colloidal silica, etc., if required. Otherwise, it comprises a dealkalized silica, obtained by removing a portion of or all sodium ions from water glass, and slaked lime as effective components and further comprises slugs, if required.</p> |
