Enhanced ecological foam light soil material and preparation method thereof

Abstract

The invention discloses an enhanced ecological foam light soil material and a preparation method thereof, and the enhanced ecological foam light soil material is composed of the following components by the mass percentage: 2%-3.5% of foam, 70%-85% of sludge slurry, 10%-20% of an environment-friendly composite curing agent, 5%-20% of an environment-friendly admixture, and 0.2%-0.6% of an early strength agent. According to the embodiment of the invention, reasonable utilization of sludge resources is realized, the problem of utilization and regeneration of solid waste resources is solved, the environment-friendly light soil is very high in environmental protection property, can be suitable for roadbed filling under different working conditions as filling soil, and has the advantages of low cost and rapidness, simplicity and convenience in construction.

Description

technical field

[0001] The invention relates to the technical field of building materials, in particular to a reinforced ecological foam lightweight soil material and a preparation method thereof. Background technique

[0002] There is a large amount of silt distributed in most coastal areas of our country, how to use this kind of silt for engineering is a big research topic. Usually, this kind 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 practical projects, and it is necessary to use solidification and stabilization technology to convert silt into geotechnical materials. A large amount of light soil needs to be backfilled in the construction of roads and underground projects. The traditional construction method is to use foam clay light soil and cement light soil for backfilling. With the shortage of high-quality clay resources and the improvement of en...
