Low-carbon road subbase material doped with water supply plant sludge as well as preparation method and application of low-carbon road subbase material
The invention discloses a water supply plant sludge doped low-carbon road subbase material and a preparation method thereof, the water supply plant sludge, a conditioner, an auxiliary agent, engineering residue soil, a soil curing agent and the like are used as raw materials, the auxiliary agent is used for adjusting the water content, grading and plasticity index of a system, and the conditioner is used for adjusting the water content and environmental safety of the system; based on the synergistic effect of the multi-source solid waste, Al2O3 and SiO2 in the soil curing agent react with Ca (OH) 2 to generate C-A-S-H, C-S-H, C-A-H gel, Aft and the like, so that the low-carbon road subbase material has good compactness, mechanical properties, water stability and environmental safety. Meanwhile, the production cost is reduced, the resource utilization level of solid wastes such as engineering residue soil, water supply plant sludge, steel slag powder and industrial byproduct gypsum is improved, and the principles of resource utilization maximization, performance optimization and economic cost optimization are realized.
