| titleOfInvention | Ground modifier for removing hexavalent chromium and lowering viscosity and method for preparing same |
| abstract | The present invention relates to a ground improver for hexavalent chromium removal and viscosity lowering, and a method for manufacturing the same, and particularly, in a cement ground improver, a reducing agent and a fluidizing agent, which are ferrous sulfate monoferrate or ferrous sulfate hexate salts. Admixing step of preparing admixture by mixing in a weight ratio of 1: 9 to 2: 8; 0.5 to 3% by weight of the admixture prepared above is added to the cement suspension in the mixer operating in the field, characterized in that the admixture step of reducing the hexavalent chromium in the cement to trivalent chromium.n n n According to the present invention as described above, by reducing the hexavalent chromium, which regulates the amount of elution in the ground improver to trivalent chromium to prevent soil pollution, by managing the viscosity of the suspension suspended in cement powder in water to 15cps or less It can improve the workability and penetration of injection material.n n n Cement, hexavalent chromium, trivalent chromium, reducing agent, glidant |
