Structural agent for light solidified sludge, solidified soil and preparation method thereof

The invention discloses a structuring agent for light solidified sludge, solidified soil and a preparation method thereof, and belongs to the technical field of solidified soil materials. The structural agent for light cured sludge is prepared from the following raw materials: a sludge curing cementing material, an anti-over-dispersion hydrogen peroxide emulsion/solution, a foaming catalyst and expanded polyphenyl granules, and the anti-over-dispersion hydrogen peroxide emulsion/solution is prepared by mixing and stirring hydrogen peroxide and a high-molecular polymer solution/emulsion. The light-weight sludge solidified soil is prepared from the following raw materials: sludge slurry to be solidified and the structuring agent for the light-weight solidified sludge. By the adoption of the technical scheme, the technical problems existing when the light sludge solidified soil is prepared through an existing physical foaming mode can be effectively solved, and meanwhile the defects that an existing hydrogen per
