AB  - This study evaluated the durability of concrete substituted with 20% Fly Ash (FA20) and concrete
substituted with 50% ground granulated Blast furnace Slag (BS50) for use in nuclear power plants. The
experimental variables were admixture type and water-binder ratio. The measured durability characteristics were
compressive strength, chloride-attack resistance and resistance to freezing and thawing. BS50 had lower initial
strength but better compressive strength as a function of aging than FA20. The results of resistance against
chloride attack and freezing and thawing showed that as the water-binder ratio decreased the resistance was
improved, regardless of admixture type. In particular, resistance against chloride attack and the mass loss rate
due to freezing and thawing in the BS50 mix were approximately 1.3 and 2.2 times higher, respectively as
compared to the FA20 mix. Conclusively, the BS50 mix was better than the FA20 mix in terms of chloride attack
and freezing-thawing durability.
