It is shown that higher contents of such nanocrystals in the hardened cement paste introduce a magnetic moment, whereas the mechanical properties remain unchanged compared to non‐blended hardened cement paste for a wide concentration range.en1522-26402023WileyAnalytical methodsHard magnetic nanocrystalsHydrated and hardened cement pasteMaterial scienceChemistryJournal Article10.1002/cite.202300022Journal Article
