    摘要: A method is disclosed for immobilizing material contaminated with heavy metal ions, said metal ions in a liquid environment being allowed to react with a metal-complexing agent with the formation of a metal complex, the metal-complex formed being mixed, in the presence of water, with an inorganic, hydraulic binder comprising blast furnace slag cement, fly ash cement or a combination thereof to form a matrix having reductive properties in the form of a hard, rocklike material, which method is characterized in that said metal complex is formed in the presence of a metal-complex bond activator. Said metal-complex bond activator is preferably a water-soluble salt of a transition metal element, expediently ferric chloride or manganese sulphate. The invention also relates to a fixant for immobilizing heavy metal ions comprised in waste material.

    摘要: Stable vermiculite dispersions which are substantially free of settling and a method of preparing them are provided: the dispersions are obtained by treating vermiculite crystals with an anionic non-citrate chelating agent. The anionic chelating agent enhances the rate and degree of swelling of the vermiculite in an aqueous medium. The swollen vermiculite is delaminated by shearing to provide the aqueous vermiculite dispersions of the invention.

    摘要: There are disclosed methods and compositions for retarding the room temperature gelation and eventual hardening of phenolic resole resins when such resins are mixed with lightburned magnesium oxide or magnesium hydroxide hardening agents with or without an ester functional hardening agent. Retardation of gelation and hardening is achieved by incorporating into said mixture a retarder compound such as one which decreases the solubility of magnesium in said mixture. Additionally, hardening at higher temperatures, thermal curing, coated abrasives, polymer concrete, and other methods and compositions of this invention are disclosed.
