Saline-soil light curing agent and method for treating saline soil with saline-soil light curing agent

Abstract

The invention provides a saline-soil light curing agent. The total weight of the curing agent serves as a standard; the curing agent is prepared from 31.8%-35.3% of cement, 18.2%-25.6% of lime, 41.0%-45.6% of coal ash and 0.9%-1.6% of aluminum powder; the cement is portland cement; the coal ash is primary coal ash; the aluminum powder is aerated aluminum powder with the standard number of JC / T 407-2000. Meanwhile, the invention provides a method for treating saline soil with the saline-soil light curing agent. The saline-soil light curing agent and the method for treating the saline soil with the saline-soil light curing agent have the advantages that by means of the curing agent prepared with the two materials of the lime and the coal ash, the curing effect is more obvious, the effect is more stable, and the cost is low; the aluminum-powder adding aim is that a soil body is expanded, and the foaming effect is achieved; the strength is guaranteed; meanwhile, the volume is increased, and the cost is saved.

Description

technical field [0001] The invention relates to the technical field of soil solidification and the field of engineering construction, in particular to a light-weight solidifying agent for saline soil and a method for treating saline soil. Background technique [0002] Soil stabilizer is a new type of energy-saving and environmental protection engineering material synthesized from various inorganic and organic materials to stabilize various soils. For the soil to be reinforced, according to the physical and chemical properties of the soil, it only needs to be mixed with a certain amount of curing agent, and the required performance index can be achieved after mixing and compacting. [0003] When the soluble salt content in the rock and soil reaches more than 0.3%, and has engineering characteristics such as dissolution, salt expansion, and corrosion, the rock and soil are called saline soil. Due to the warming in spring and dry air in saline soil, the salinity rises to the s...

AI Technical Summary

Problems solved by technology

Saline soil has a high bearing capacity in its natural state, but it is prone to dissolution and subsidence when it encounters water, which is very harmful to the upper structure, and damage phenomena such as uneven settlement of buildings caused by immersion and softening of chlorine saline soil not uncommon

At present, there is no effective and reasonable treatment method for saline soil, especially saline soil foundation and roadbed filling with high salt content. It is urgent to provide an effective, economical and reasonable curing agent and treatment method.
