Abstract

The invention discloses physical-foaming silty lightweight solidified soil. The physical-foaming silty lightweight solidified soil comprises, by mass, 2-3.5% of foam, 80-85% of sludge slurry, 12-16% of inorganic composite curing agents, 0.1-0.2% of viscosity reducer and 0.2-0.5% of early strength agent. The invention further discloses a preparation method of the solidified soil. The lightweight solidified soil has the advantages of light weight, high strength, high stability, easiness in pumping, and the like; sludge is regarded as an important component of the lightweight solidified soil, theresource utilization of the sludge is realized, and the environmental protection advantage is prominent; the lightweight solidified soil can be used as filling soil to be backfilled for highway subgrades and abutments, retaining wall backs, underground projects and pipeline projects; the physical-foaming silty lightweight solidified soil is an environment-friendly building material.

Description

Technical field [0001] The invention relates to the field of new building materials, in particular to a physical foaming silt lightweight solidified soil and a preparation method thereof. Background technique [0002] A large amount of silt is distributed in most coastal areas of our country. How to use this silt in engineering is a big research topic. Under normal circumstances, this type of sludge has the characteristics of high water content, large void ratio, high compressibility and low strength. Therefore, it is difficult to directly apply silt to actual engineering, and it is necessary to use solidification and stabilization technology to convert silt into geotechnical materials. A large amount of lightweight soil needs to be backfilled in the construction of roads and underground projects. The traditional construction method is to use foamed clay lightweight soil and cement lightweight soil for backfilling. With the shortage of high-quality clay resources and the increas...
