HARDENABLE OR SETTABLE MATERIAL AND METHOD FOR STABILISING CSG SALTS

摘要

A hardenable or settable material comprises a hydraulic binder and particles of solid salt, the particles of solid salt containing NaCl and Na2CO3. The salt may also contain NaHCO3. The material may be used to fill voids in mines or disposed of in regulated waste facilities. The material has a high content of solid salt and a low content of binder. Water or brine (such as CSG derived brine) is suitably added in an amount that does not result in dissolution of the salt.
