Abstract

The invention discloses a green low-carbon curing agent for soil curing. The soil curing agent is characterized by comprising granulated blast furnace slag micro powder and exciting agent, wherein the exciting agent comprises active magnesia, the exciting agent is 30 to 5 percent of the total mass of the soil curing agent, and the granulated blast furnace slag micro powder is 70 to 95 percent of the total mass of the curing agent. The exciting agent comprises slaked lime, wherein the slaked lime is 10 to 90 percent of the mass of the active magnesia. The exciting agent comprises calcined lime, wherein the calcined lime is 7 to 66 percent of the mass of the active magnesia.

Description

technical field

[0001] The invention belongs to the technical field of civil engineering, and is a green and low-carbon environment-friendly curing agent for curing soil. Background technique

[0002] Mixing pile technology (wet method, dry method) is one of the effective methods to strengthen the soft soil foundation. It sprays the curing agent (slurry or dry powder) into the soft soil while drilling through the deep mixing machine, and mixes the soft soil and The curing agent is forced to stir, and through the physical and chemical interaction between the curing agent and the soft soil, the solidified soil with high strength, integrity and good water stability is formed. The traditional mixing pile curing agent is mainly cement and quicklime. Quicklime is the main curing agent in the early stage of mixing pile technology (the late 1970s), but its disadvantage is that the strength of the formed mixing pile is too low, especially the effect of soft soil foundation treatment...
