In the present age, the concrete material is playing an increasingly important role in construction. But in the meantime, environmental features have serious damaging influence on the concrete. Consequently, this damage will decline the long-time persistence and serviceability of concrete structures. This review paper discusses recent researches activity on the permanence of concrete, including: a) main durability problem including sulfate attack, steel corrosion and alkali aggregate reaction, b) durability of concrete in nautical location such as seawater, groundwater, Salt Lake; and c) mix with effects of environmental items and mechanical loads on persistence of concrete. This report is based on results of many realistic experiments which happened by scientist. Consequently, it’s important to follow these methods to improve service life of concrete and durability would be superior.
