| Popis: | The prospects of boron-containing liquid radioactive waste (LRW) solidification using cement with geopolymer binders have been considered. It is known that geopolymer compounds can be produced on the basis of industrial wastes – ground slag from metallurgical plants, TPPs’ ash-slag, etc. Geopolymers may comprise alkalis that are part of LRW. The strength of geopolymers may increase by 1.5 – 2 times over time. The synthesis of geopolymers does not pollute the air with CO2. The properties of a LRW simulator, which was a concentrated salt solution at the temperature above 60 °C, were taken into account. During the cooling of the simulator, the phenomena of hypothermia and spontaneous crystallization of sodium metaborate have been observed. If |
