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 ...
