Migration Patterns of Sulfate Ions within Concrete Under Wet-Dry Cycling in the Saline Soil Region of Western Jilin, China

Boxin Wang Tianlve Wang Xu Chai Xinyu Lu Guangze Bi

This paper aims to investigate the migration behavior of sulfate ions within concrete under wet-dry cycling conditions and their impact on concrete erosion. The study delves into the coupled effects of sulfate attack and wet-dry cycles on concrete degradation. By utilizing Scanning Electron Microscope (SEM) experiments to examine the microstructural characteristics and morphologies of chemical crystalline substances within concrete, the erosive mechanisms and the damage induced by sulfate ions at the microscale are examined. Building upon diffusion theory, this paper establishes a transport model for sulfate ions in concrete, providing a basis for predicting the erosion time and depth. Findings hold significant implications for the durability assessment and safeguarding of concrete structures in the saline soil region of Northeast China against the erosive impact of sulfate ions.
