DISPERSANT FOR PREMIXED FLUIDIZED SOLIDIFIED SOIL, PREPARATION METHOD AND APPLICATION THEREOF
A dispersant for premixed fluidized solidified soil includes the following raw materials in parts by weight: 5 parts to 15 parts of an anti-adhesion water reducer, 0.5 parts to 0.8 parts of a stabilizer, and 85 parts to 95 parts of water. The anti-adhesion water reducer is compounded by an inorganic dispersant and an aminosulfonic acid-based superplasticizer (ASP), and the inorganic dispersant is at least one selected from the group consisting of sodium silicate, sodium hexametaphosphate, and sodium pyrophosphate. In the present disclosure, on the premise of improving fluidity of mucky cohesive soil slurry, a strength of the fluidized solidified soil at each stage is adjusted through a water-reducing effect of the anti-adhesion water reducer. Moreover, rapid dispersion of the mucky cohesive soil slurry is realized, thus providing key technical support for preparation of the premixed fluidized solidified soil from undisturbed soil in non-dry conditions.
