NEW GEOLOGICAL CEMENT FOR SOLIDIFYING RADIOACTIVE EVAPORATION RESIDUE AND METHOD FOR SOLIDIFICATION

Provided is a new geological cement material and a method for the solidification thereof, belonging to the technical domain of radioactive evaporation residue solidification. The method involves preparing a geological cement by means of uniformly mixing aluminosilicate-containing slag, a compound mineral activator, and a sorbent. The geological cement is then mixed with concentrated liquid wastes and stirred for 7 minutes in an agitation vessel, then transferred to a mold for curing. When using same to solidify liquid radioactive evaporation residues, the dry salt content whereof is as high as 345g/l, the liquid evaporation residue content of the solidified form is as high as 80%, the setting time is adjustable and terminable within 24 hours, and the initial setting period is sure to be suitable for performing solidification operations. After curing for 28 days, all indicators of the solid form exceed the requirements of the "National Performance Requirements for Low- and Intermediate-Level Radioactive Waste
