چکیده مقاله
Corrosion of prestressed concrete, particularly the degradation of tendons and reinforcement, jeopardizes infrastructure safety and longevity, especially in chloride rich environments like marine, industrial, and de icing areas This review examines advanced corrosion mitigation strategies, including corrosion inhibitors, cathodic protection, high performance concrete HPC , and post tensioning strand coatings Corrosion inhibitors, such as calcium nitrite, modify electrochemical reactions to protect reinforcement, while cathodic protection systems effectively halt corrosion but require maintenance HPC enhances durability by reducing permeability and improving steel concrete bonding, delaying corrosion onset Post tensioning strand coatings provide additional defense by blocking moisture and chlorides Case studies illustrate the effectiveness of these methods in extending service life and minimizing maintenance costs A multi layered prevention approach is recommended for optimal results The paper also highlights the need for future research to improve cost efficiency and monitoring technologies, ensuring the sustainability and safety of prestressed concrete structures in aggressive environments
