Abstract

A process for the production of agglomerates which are resistant to leaching out, from finely divided waste materials, is characterized in that a hydraulic binding agent is dissolved in water under a condition of forced mixing until it substantially no longer sediments, the resulting aqueous colloidal solution is combined with the finely divided waste materials and in so doing the water content of the mixture is adjusted to an agglomeratable consistency, the mixture is agglomerated through mixing, and then hardened.
