AI Technical Summary
Technical Problem
The engineering performance and durability of dredged silt solidified soil are easily degraded under external loads and environmental factors, affecting the safety of filling projects, and existing solidifying agents are not economical.
Method used
Quicklime was used to stabilize the dredged silt, and high-concentration CO2 mineralization was applied. Combined with iron oxide catalytic reaction, strongly cemented CaCO3 was generated. The prefabricated roadbed was formed by stamping, simulating the natural diagenetic process.
Benefits of technology
It improves the strength and durability of dredged silt-stabilized soil, enhances the stability of the roadbed, reduces construction costs, and achieves efficient resource reuse and environmentally friendly construction.
