PROBLEM TO BE SOLVED: To obtain a grouting consolidation material which has high strength and excellent durability in spite of a low silica concentration and exhibits a long gelling time and enables seepage into a wide range as the grout for preventing the liquefaction of ground. SOLUTION: A grouting consolidation material is obtained by mixing water glass with colloidal silica or further mixing the resulting mixture with 3-13 wt.% active silicic acid to form a stabilized alkaline silica solution as the base which is non-self curable in itself or further subjecting the resulting alkaline silica solution to dealkalization treatment to form a dealkalized silica solution as the base, and further adding an acidic reactant, another reactant, cement, slag and the like to the base. |
