[1116] COMPREHENSIVE NUMERICAL SYSTEM FOR PREDICTING AIRBORNE CHLORIDE GENERATION AND ITS INGRESSION INTO CONCRETE UNDER ACTUAL ENVIRONMENTAL CONDITIONS

In marine environments, the deterioration of RC structures is caused by airborne chloride attacks. The structure used in coastal areas often requires repair due to the corrosion problem. Thus, this research aims to develop a comprehensive system that can predict chloride ingression into the concrete structures. The system can be used to determine the amount of airborne chloride generated by breaking waves, transported by wind flow, and ingression through the concrete surface at specified times and positions. The proposed framework is verified through onsite measurements to confirm its validity.
