AI Technical Summary

Technical Problem

Due to its poor stability, easy liquefaction, difficulty in compaction, easy to absorb water and freezing in engineering construction, the foundation strength is reduced and the engineering life is shortened. The existing curing agents are not mature enough in the curing of silt.

Method used

A multi-source solid waste silt solid agent is used, which consists of basalt solid waste, waste concrete powder, slag, alkaline exciter, sodium gluconate and polypropylene fibers. The strength and stability of silt are improved through alkaline excitation reaction and gelling.

Benefits of technology

It significantly improves the strength and stability of silt, can meet the control indicators of roadbed projects such as highways, extends the service life of the project, and reduces construction costs.

Abstract

The invention discloses a multi-source solid waste silt curing agent as well as a preparation method and application thereof, and belongs to the technical field of silt curing. The multi-source solid waste silt curing agent is prepared from the following raw materials in percentage by mass: 20 to 30 percent of basalt solid waste, 5 to 10 percent of waste concrete micro powder, 15 to 25 percent of slag, 20 to 35 percent of alkaline excitant, 5 to 15 percent of sodium gluconate and 5 to 10 percent of polypropylene fiber. Most of the raw materials of the multi-source solid waste silt curing agent are derived from industrial wastes, the cost is low, and compared with a cement curing agent, the multi-source solid waste silt curing agent has a better silt curing effect and can achieve required engineering characteristics.
