ANNOTATION:

The paper explores mechanical, physical, chemical and structural properties of cement compounds based on blastfurnace slag produced in metal containers using the hot isostatic pressing (HIP) method. The study allowed to evaluate the radiation resistance of cement compounds under the influence of ionizing radiation up to an absorbed dose of 109 Gy and 1019 alpha-dispersion/g. The tests confirmed that the matrices complied with the established regulatory requirements. It was demonstrated that cement compound synthesis based on the HIP method provided matrices with enhanced physical and chemical characteristics. It was also shown that under radiation exposure, cement compounds containing high-level waste simulators retained their properties and structure.

Keywords: radioactive waste, cementation, hot pressing, metal container, compressive strength, structure, radiation resistance.
