ABSTRACT:
The present invention generally relates to a method for hydraulically backfilling empty mined salt cavities. The method comprises combining at least one pozzolanically active waste material with an effective amount of a cementing agent and brine to form a pozzolanic mixture, wherein the relative proportions of said pozzolanically active waste material, alkaline earth metal hydroxide or alkaline earth metal oxide and saturated brine are sufficient for reaction under conditions in said salt cavity to form a stable, low porosity, load bearing pozzolanic cement; oxidizing said pozzolanic mixture in order to substantially remove aluminum metal from the mixture; and hydraulically depositing said pozzolanic mixture in the empty salt cavity.
