Study on Durability of New Concrete Materials in Marine Environment

Abstract

Concrete structures in marine environments are often subjected to multiple factors such as saltwater erosion, seawater corrosion, and physical impacts, leading to their deterioration and damage. This paper analyzes the mechanisms of concrete deterioration in marine environments and proposes strategies to enhance the durability of new concrete materials in such settings. These strategies include the use of high-performance concrete, the addition of corrosion inhibitors, increasing the thickness of concrete protective layers, surface coatings for protection, and the incorporation of high-performance mesh fibers, among others. These approaches are expected to prolong the service life of concrete structures, reduce maintenance costs, and support sustainable marine infrastructure development.
