METHOD AND MATERIAL FOR TREATING SOLID AND SEMI-SOLID WASTE MATERIALS CONTAINING REACTIVE SULFIDES

摘要

A method and material is provided for treating solid and semi-solid waste materials containing reactive sulfides wherein from about 60 % to about 90 % of a solid or semi-solid waste material containing reactive sulfides is mixed with from about 5 % to about 40 % hydraulic cement, from about 5 % to about 40 % metal carbonate, and from about 0 % to about 15 % water. The mixture is allowed to cure and the resultant end product is a physically and chemically stable solid material with a reduced concentation of reactive sulfides. The reactive sulfides remaining in the material are permanently encapsulated in the monolithic mass.
