Embodiment 1
[0031] First prepare the soil stabilizer: the weight ratio of overburned magnesia and potassium dihydrogen phosphate is 1.18, that is, the ratio of the amount of magnesium in the overburned magnesia to the amount of phosphorus in potassium dihydrogen phosphate is 4, and the boric acid content It is 4% of the mass of perburned magnesium oxide, and the three are mixed uniformly.
[0032] Add water to dissolve, the water to be added is 18% of the sum of the solid mass of potassium dihydrogen phosphate and perburned magnesium oxide, and stir evenly.
[0033] Then pour the soil and curing agent into the mixer, the content of the curing agent is about 15% of the weight of the soil, after stirring evenly, according to the requirements of the geotechnical test specification, the sludge is made into a diameter of 3.91cm and a height of 8cm After the sample preparation is completed, it is placed in the curing room, demoulded after five hours, the measured unconfined compressive strength...
Embodiment 2
[0035] On the basis of Example 1, only the weight ratio of curing agent to contaminated soil was adjusted to 20%, the unconfined compressive strength of the obtained sample block was about 320kPa, and the pH value of the consolidated soil was 9-10. The concentration of the heavy metal leach solution meets the specification of GB 5085.3-2007 "Identification Standards for Hazardous Wastes - Identification of Leaching Toxicity".
Embodiment 3
[0037] On the basis of Example 1, the weight ratio of overburned magnesium oxide and potassium dihydrogen phosphate is adjusted to 1.1, that is, the ratio of the amount of magnesium in the overburned magnesium oxide to the amount of phosphorus in potassium dihydrogen phosphate is 3.74, the unconfined compressive strength value of the obtained sample block is about 250kPa, and the pH value of the solidified soil is 9-10. The concentration of the heavy metal leach solution meets the specification of GB 5085.3-2007 "Identification Standards for Hazardous Wastes - Identification of Leaching Toxicity".
