Compound heavy metal solidifying agent for governing contaminated soil and preparation method thereof
The invention provides a compound heavy metal solidifying agent for governing contaminated soil. The compound heavy metal solidifying agent is prepared from the following raw materials in percentage by weight: 15-40wt% of cement, 50-70wt% of steel slag powder, 4-10wt% of gypsum and 2-10wt% of an excitant. The invention further discloses a preparation method and application of the compound heavy metal solidifying agent for governing contaminated soil. The prepared solidifying agent is good in application effect, can be used for effectively reducing the content of compound heavy metals in soil and meanwhile can be used for continuously enhancing the long-term strength of the solidified soil. The mechanical property of the solidifying agent can be used for fully satisfying the request of use of building materials such as subgrade construction and the like. Moreover, the preparation method is relatively simple and low in cost and has important actual significance.
