TP24-22 Modeling Deterioration and Predicting Service Life of Concrete Cooling Towers Winter Operation

TP24-22 Modeling Deterioration and Predicting Service Life of Concrete Cooling Towers Winter OperationHyperbolic natural draft cooling towers and other concrete structures can experience various types and degrees of concrete deterioration caused from years of service in industrial operating environments. Concrete erosion, corrosion of embedded reinforcement, and other deterioration mechanisms can introduce operational risks and significantly reduce the integrity of the structure, ultimately leading to the end of service life. To manage cooling tower
