Electrochemical protection against corrosion for steel bars in reinforced concrete structures exposed to seawater
https://doi.org/10.22349/1994-6716-2018-96-4-185-190
Abstract
The paper analyzes ways to ensure long service life (up to 50 years) of reinforced concrete marine structures. It has been established that durability and maintenance-free operation of floating and coastal offshore structures for 50 and more years depend on corrosion of steel reinforcement which could be avoided by applying electrochemical protection. The parameters of electrochemical protection against corrosion of steel fittings are given.
