Abstract

The invention provides a water-resistant polluted soil repair solidifying agent. The water-resistant polluted soil repair solidifying agent is characterized by being prepared from the following components in parts by weight: 4-6 parts of ordinary Portland cement, 35-45 parts of an adhesive, 15-25 parts of an enhancer, 2-6 parts of an early strength agent, 4-9 parts of a waterproof agent, 5-9 partsof a filling agent, 2-4 parts of a water reducing agent, 0.3-0.7 part of a surfactant, 1-3 parts of a dispersing agent, 0.01-0.03 part of a retarder, 0.01-0.03 part of an air entraining agent and 8-11 parts of a blending emulsifier. The blending emulsifier comprises the following materials in parts by weight: 50-60 parts of an emulsifying agent, 10-14 parts of grease, 3-6 parts of a water-solublepolymer, 2-4 parts of a stabilizer and 10-20 parts of methyl eicosapentaenoate.

Description

technical field [0001] The invention relates to the technical field of soil solidification, in particular to a water-resistant polluted soil remediation solidifying agent. Background technique [0002] Contaminated soil remediation refers to the use of physical, chemical, biological and ecological principles and artificial control measures to reduce the concentration (activity) of soil pollutants to achieve harmless and stable pollutants, so as to achieve the desired detoxification effect. technical measures. At present, the theoretically feasible remediation technologies include phytoremediation, microbial remediation, chemical remediation, physical remediation and comprehensive remediation. Some repair technologies have entered the stage of field application and achieved good results. The remediation of contaminated soil is of great significance to blocking the entry of pollutants into the food chain, preventing harm to human health, and promoting the protection of land ...
