METHOD OF TREATMENT OF DREDGED MATERIAL FOR BENEFICIAL USE

摘要

A method for the decontamination and solidification of dredged material is described. The method includes, in the following order, (a) adding a lime-based binder to dredged material to form a mixture; (b) letting the mixture cool to about ambient temperature; and (c) adding to the mixture a chelating agent. The order of the steps may not be reversed without affecting the effectiveness of the treatment of the dredged material. A method for producing filler containing decontaminated and solidified dredged material i s also described. The method includes treating dredged material with a lime-based binder and a chelating agent and adding the resulting mixture to concrete.
