Self-curing type fluid stabilized soil composite curing agent and application thereof

The invention discloses a self-curing type fluid stabilized soil composite curing agent and application thereof. The composite curing agent is prepared from the following raw materials: 30-35% of cement, 10-20% of slag, 10-20% of gypsum, 5-8% of carbide slag, 30-39% of a microbial curing agent and 1-5% of self-curing microbeads. According to the method, the compressive strength of the fluid-state solidified soil can be effectively improved while the early-stage fluidity of the fluid-state solidified soil is guaranteed, shrinkage deformation of the fluid-state solidified soil is inhibited, and the durability of the fluid-state solidified soil is improved. The method improves the recycling rate of solid waste resources, has the characteristics of low cost, remarkable environmental protection effect and the like on the premise of ensuring the application effect, and is suitable for large-scale popularization and application; the self-curing composite curing agent is wide in raw material source, simple in prepara
