Abstract
The present invention relates to a soil solidifying agent prepared by the mixed preparation of concentrated sulfuric acid and/or concentrated hydrochloric acid, Na2 SO4, sulfonates, early strength agents, FeSo4 and/or FeCl3 and YW type fluorine-class surface-active agents. The soil solidifying agent has the advantage of simple preparation technology and provides convenience for the construction of roadbeds and road surfaces. All technical indexes of the soil solidifying agent reach state-specified standards and also has the advantages for decreasing the dosage of traditional road building materials, such as calcium oxide and cement, improving the water immersion resisting capacity and the freeze-thaw resisting performance of the roadbeds and road surfaces, enhancing the whole intensity of the roadbeds and road surfaces, greatly reducing engineering cost, extending the service life of roads, reducing the maintenance cost of roads. The soil solidifying agent can also be used for the construction of water conservancy dams and urban facilities.
Description
Technical field:
The present invention relates to a kind of soil solidifying agent, especially relate to a kind of soil solidifying agent that is used for highway subgrade and sub-surface.
Background technology:
Highway subgrade and sub-surface need certain intensity, material damage ecology, contaminate environment such as traditional sandstone, lime, cement, do not meet the requirement of building a resource-conserving and environment-friendly society, especially discharge a large amount of carbon dioxides in lime, the Cement Production process, the aggravation Global Greenhouse Effect.
Summary of the invention:
Technical problem to be solved by this invention provides a kind of soil solidifying agent that improves roadbed, pavement strength, water stability, freezing stability, reduces the consumption of traditional road-making material, reduces the construction costs of highway, and the later maintenance expense.
Soil solidifying agent of the present invention is formed by weight percentage and is comprised:
The vitriol oil and/or concentrated hydrochloric acid 20-35%
Na
2SO
4 20-30％
Sulfonate 10-20%
Hardening accelerator 5-10%
FeSO
4And/or FeCl
310-20%
YW type fluorine class tensio-active agent 1-5%.
Sulfonate is sulfamate or naphthyl sulfonate.
Hardening accelerator is three b propanol amine or trolamines.
Sulfonate can improve the water-fast ability of soaking of the soil body among the present invention in the soil body of compacting; Hardening accelerator can quicken the curing after the subgrade and pavement material compaction; YW type fluorine class tensio-active agent can reduce the surface tension of soil particle planar water significantly under acidic conditions, make it be separated into more tiny soil particle, redundant moisture is discharged or evaporation, thereby reduced the gap of soil particle after the compacting of subgrade and pavement mixing material, improve degree of compactness, thereby improved intensity.
Soil solidifying agent of the present invention is convenient to the subgrade and pavement construction, every technical indicator all reaches state specified standards, can reduce the consumption of traditional road-making material such as lime, cement, improve the water-fast ability of soaking and the freezing and thawing performance of subgrade and pavement, improve the subgrade and pavement bulk strength, reduced construction costs significantly, prolonged the working life of highway, reduce the maintenance costs of highway, the present invention can also be used for water conservancy dam construction and urban operating mechanism construction.
