PURPOSE: A soil hardener composition is provided to allow a suitable strength to be maintained even with using common soil by salts as a strength enhancer, thereby reducing cost. CONSTITUTION: The soil hardener composition comprises 100-300 kg of cement; 200-400 liter of water; and 25-300 mol of at least one compound selected from the group consisting of sodium sulfate, potassium sulfate, sodium carbonate, potassium carbonate, sodium chloride, potassium chloride, sodium phosphate and potassium phosphate, as a strength enhancer, based on 1 m3 of soil having a density of 1.1-3.0. Preferably the strength enhancer is a mixture of at least one selected from the group consisting of sodium sulfate, potassium sulfate, sodium carbonate and potassium carbonate and at least one selected from the group consisting of sodium chloride and potassium chloride in the ratio of 1 : 0.1-0.5 by mol. |
