Embodiment 1
[0028] Embodiment 1 Get each raw material component of soft soil solidifying agent by following weight ratio:
[0029] The powder raw material is: P.O42.5 ordinary Portland cement.
[0030] The raw material composition of the solution is: anionic polyacrylamide 5kg, pulp waste liquid 45kg, cement retarder 45kg, OP-10 industrial emulsifier 2.0kg, carrageenan 0.5kg, xanthan gum 0.5kg, sodium α-olefin sulfonate 2.0kg, mixed with 3 times water to make a liquid.
[0031] Calculate the amount of water needed to be added to the cement according to the water-cement ratio of 0.45, mix it with the liquid agent evenly, and then mix it with cement to make a cement slurry for use. The ratio of cement and liquid agent is about 50:1, and use the prepared cement slurry to solidify the sludge. Knot treatment test. The test uses the silt blowing and land reclamation silt from Lingang New District, Tianjin. It has been determined that the water content of the silt is about 100%, and the organi...
