成する。 When soil is solidified with cement, organic substances such as humic acid contained in the soil inhibit the solidification reaction of the cement, making it impossible to form a solid substance with sufficient strength. The organic matter contained in the soil is removed by reacting with magnesium chloride, potassium chloride, calcium chloride, sodium chloride, sodium sulfate, cobalt chloride, and their catalysts, ammonium chloride and citric acid, and the soil is thoroughly cemented. Can be solidified with strength. By adding barium oxide and its catalysts, calcium sulfate, calcium phosphate, manganese dioxide, sodium sulfite, and carbon, to the liquid phase of cement, oxygen is added during the solidification process until the liquid phase changes to the solid phase. is continuously generated to prevent the voids between soil particles from being clogged with liquid cement, thereby forming a porous body having a large number of large-capacity continuous pores (continuous voids).

を上記範囲で選択して使用するのが望ましい。 If the amount of potassium chloride is less than 200g , the permeability of calcium ions in the cement will be poor, and if it is more than 300g, it will not only be difficult to dissolve, but the effect of imparting permeability to calcium ions will be improved. do not. If magnesium chloride is less than 150g, a contraction clutch will occur in the pore structure,
If it is more than 200g, the pore structure will expand. If calcium chloride is less than 150g, the strength of the pore structure cannot be enhanced, and if it is more than 200g, the pore structure may be destroyed due to water rupture. If sodium chloride is less than 100g,
The calcium ion penetration ability of cement is poor,
If the amount exceeds 150 g, not only will it be difficult to dissolve, but the effect of imparting penetrating power to calcium ions will not improve. If ammonium chloride is less than 100 g, each component will be difficult to dissolve, and if it is more than 120 g, the strength of the porous structure will be reduced. If the amount of sodium sulfate is less than 20g, the cement cannot be rapidly hardened, and if it is more than 30g, the long-term stability of the strength of the cement will be poor. If the amount of citric acid is less than 10 g, each component will be difficult to dissolve, and if it is more than 20 g, the strength of the porous structure will decrease. If cobalt chloride is less than 1 g, the ionic activity of each component cannot be activated, and if it is more than 2 g, not only will the effect not be improved, but it will also be expensive. In addition, barium oxide, calcium sulfate, calcium phosphate, manganese dioxide, sodium sulfite and carbon (each in weight ratio
