GGBFS, referred to in the radiation shielding section, is not defined.
[edit]From context, it is a substitute for cement. The linked article defines it as "Ground granulated blast furnace slag". I have no very clear idea of the composition or trade-offs around that. ArthurDent006.5 (talk) 23:44, 29 January 2026 (UTC)
