Study on the Vulnerability of Metals and Proposed Solutions to Prevent Corrosion of Structures in Salt - Brackish Water Environments

Abstract

This article studies the basis of metal corrosion process, corrosion rate, characteristics and factors affecting metal corrosion rate in salt water-brackish water environments, conducted in downstream areas of large rivers and coastal areas. Then, the study proposes anti-corrosion measures to increase the life of metal structures and reduce the destruction of steel reinforcement in concrete, thereby applying them to the design and manufacture of structures, equipment used in salt water-brackish water environments, projects on estuaries and coastal areas, including defense, transportation, construction, civil and industrial projects in areas vulnerable to intrusion salinity, climate change, etc. The process of metal destruction in saltwater-brackish water environments is analyzed through chemical reactions that destroy metals, reducing their load-bearing capacity, leading to destruction of works that use many metal structures. To tackle this situation, the authors have proposed effective solutions for practical application.
