Soft foundation silt curing agent

Abstract

The invention provides a soft foundation silt curing agent which comprises main gel powder, auxiliaries and a liquid agent, wherein the main gel powder comprises cement clinker, slag, lime, sulfate and vermiculite powder; the auxiliaries include an accelerator, an auxiliary gelling agent, an early strength agent and a water reducing agent; the liquid agent comprises polyacrylamide, polyaluminum chloride, mannitol, lignosulfonate, alkylphenol polyoxyethylene ether, tannic acid and alpha-olefin sulfonate; the accelerator is water glass; the auxiliary gelling agent is one or a mixture of two of fly ash, silicon ash and aluminum ash; the early strength agent is a mixture of sodium sulfate, aluminum sulfate and triethanolamine; and the water reducing agent is a naphthalene high-efficiency water reducing agent. By adopting the soft foundation silt curing agent provided by the invention, the problem that the silt is hard to cure due to the high organic content is solved, the silt strength is greatly improved, and the pavement performance of the silt is improved so as to meet the construction requirements as pavement subbase course and base course packing.

Description

technical field [0001] The invention belongs to the technical field of chemicals for soil treatment, in particular to a chemical for solidification treatment of soil with different water contents and its application. Background technique [0002] In recent years, highways have become more and more important in the comprehensive transportation system of my country's national economy. However, with the rapid development of highways, environmental pollution and resource shortages have also emerged one after another. It is necessary to seek to reduce environmental pollution, reduce road area ecological losses and make full use of Waste control is a long-term and arduous task in road construction at the present stage. my country has a vast territory, numerous rivers and lakes, and the amount of silt is very large. However, the engineering characteristics of silt are very poor, mainly manifested in high particle content, high water content, high compressibility, low strength, poor ...
