Cements based on alkaline earth compositions for radiation protection systems
Halyna Shabanova, Viktoriia Taranenkova, Alla KorohodskaAbstract
As a result of theoretical and experimental studies of the ternary systems CaO‐BaO‐Al 2 O 3 and CaO‐BaO‐Fe 2 O 3 , promising compositions suitable for the synthesis of new compositions of special cements with a set of specified operational properties were identified. Depending on the phase composition, a complex of certain physical, mechanical and technical properties, and also directions of application, the basic compositions of sacrificial binders based on compositions of the optimized concentration range were selected as rational and optimal: BaAl 2 O 4 ‐CaAl 2 O 4 ‐BaCa 2 Al 8 O 15 in CaO‐BaO‐Al 2 O 3 system and Ca 2 Fe 2 O 5 ‐Ba 2 Fe 2 O 5 cross‐section in CaO‐BaO‐Fe 2 O 3 system, which can be used to create passive protection systems for nuclear facilities.
