Curing agent for curing marine poor subsoil

Abstract

The invention relates to a curing agent for curing marine poor subsoil, which belongs to the technical field of poor subsoil curing. The curing agent for curing the marine poor subsoil is composed by the components of cement clinker, granulating slag or slag, silica fume, polycarboxylic acid type water-reducer, lime, plaster, anhydrous sodium sulphate, caustic soda, sodium silicate and sodium fluosilicate. The adulteration amount of the poor subsoil curing agent is 5%-12% in application, good curing functions can be realized, and the curing agent for curing the marine poor subsoil can be applied in the poor soil curing of building sites, road embankments, roadbeds and ground base layers. The invention has the advantages that: the components of the curing agent are simple, the compatibility is reasonable, the doping amount is less, and the curing effect is good; and during the application process, the construction period is short, the construction cost is low, the induration bearing capacity is high, the induration compression modulus is strong, and the induration permeable resistance is strong.

Description

technical field [0001] The invention relates to a curing agent, in particular to a curing agent for curing marine soft soil, and belongs to the technical field of soft soil curing. Background technique [0002] Igneous rocks or sedimentary rocks on land have experienced climate change for millions of years, rocks are weathered and crushed, and fine rock and soil particles are transported by inland rivers or coastal tidal hydraulics. Siltation and sedimentation form a weak soil layer, and at the same time, it will also carry upstream domestic and industrial pollutants. [0003] Because weak soil layers generally have the characteristics of fine particles, high organic matter content, high moisture content, and difficulty in precipitation, etc., resulting in low bearing capacity, high porosity, and large settlement after loading, it is difficult to directly use them as building foundations. Therefore, with the development of national economic construction, there will inevitab...

AI Technical Summary

Problems solved by technology

However, when cement-based inorganic materials are used for consolidating soft soils such as silt, the amount of admixture is relatively large, and the unconfined compressive strength is low; if cement is used to consolidate high water content (90% to 1500%) When the mixing amount of mud is in the range of 12% to 30%, the unconfined compressive strength after 28 days of consolidation is only 0.1MPa to 0.6MPa

There is also the use of adding a large amount of inorganic materials such as fly ash, lime, slag, slag, etc., but its disadvantage is that the amount of addition is as high as 25%-60%, and the source of these materials is inconvenient, the transportation volume is large, and it is difficult to popularize and apply in a large area
