Abstract: Abstract In marine environment, due to the effect of chloride ion, sulfate, magnesium ions, dry-wet cycle, and freeze-thaw cycle, the damage of reinforced concrete bridge pier is extremely serious. Reactive powder concrete, which is considered as a kind of green high performance concrete, has high durability, high strength and presents good environmental protection performance. It is especially suitable for using as protection structure of reinforced concrete bridge pier in marine environment. Through the simulation of the actual service environment, dry-wet and freeze-thaw cycles are applied in durability experiments. The mass and relative dynamic elastic modulus variation of reactive powder concrete is investigated, and the rules are also discussed. The results indicate that the seawater corrosion resistance of reactive powder concrete is satisfactory, which provides design reference for reactive powder concrete pier protection in marine environment. Reactive powder concrete is suitable for marine engineering concrete protection structure as permanent template or maintenance component.
