PURPOSE:To solidify the ground firmly without causing gelation during pouring operation and leaving Na ion and an acid group in the ground, by blending a gelatinizing agent containing an electrolyte substance with a colloidal solution of silicate, pouring the blend into the ground. CONSTITUTION:A gelatinizing agent containing an electrolyte substance (one preferably using both an electrolyte substance dissociating metallic ion such as alkaline earth metallic ion, aluminum ion, iron ion, etc., electrolyte substance dissociating hydrogen ion, or electrolyte substance dissociating calcium ion and gypsum, slag, or fly ash) is blended with a colloidal solution of silicate (preferably one containing 0.2-4wt% Na2O obtained by an alkaline metallic ion from liquid alkali metal silicate by an ion exchange resin), and the blend is poured into the ground. |
