Abstract

Chloride ions in marine environment can significantly accelerate the corrosion of steel bars in concrete structures, which threaten the safety and durability of engineering structures. This paper presents a method for the corrosion determination of steel bar in concrete structures in marine corrosion zones. Based on the simulation chamber which can reproduce the actual corrosion environment in atmosphere, wave, tide, immersion and buried zones, the volume loss rate of the corroded steel bar in the total corrosion area is quantitatively analyzed with the three-dimensional scanning technology, and the rule of the vertical corrosion rate of the concrete structure in the total corrosion zones is obtained. The test results show that the method can accurately simulate the corrosion characteristics of steel bars in the complex environment of the total corrosion zone. The test method also provides a scientific basis for the life evaluation and durability design of reinforced concrete structures.
