The durability of concrete has attracted significant attention over the past several decades and is still a research hotspot until now.This paper reviews and discusses recent research activities on the durability of concrete,including: 1) major durability problems such as alkali aggregate reaction, sulfate attack, steel corrosion and freeze-thaw;2) durability of concrete in marine environment;and 3) coupling effects of mechanical load and environmental factors on durability of concrete.Moreover, the consideration of durability in concrete structure design (DuraCrete and performance-based specifications) is also briefly reviewed.
