Impact of Key Parameters on Chloride Concentration
Understanding Chloride Penetration Dynamics
Partial Dependence Plots (PDPs) reveal complex, non-linear relationships. Fine aggregate initially reduces CC but excessive amounts can increase porosity. Exposure type significantly influences CC, with sharp increases from type 0 to 2. Exposure time (t) shows CC increasing rapidly in the first 10 years, then stabilizing. Chloride content exhibits a rising SHAP value with greater proportions. These insights are crucial for optimizing concrete mix designs for enhanced durability in marine environments.
