Natural draft hyperbolic cooling towers are extremely conducive to corrosion-induced deterioration. Exposure conditions and the resulting deterioration vary depending on a host of factors, however, by understanding the deterioration mechanisms as well as effective rehabilitation strategies, the life and value of natural draft hyperbolic cooling towers can be maximized. Further, because of the progressive nature of corrosion deterioration, the consequences and costs associated with delaying repairs can be significant. A variety of state-of-the-art concrete repair technologies, augmented with high performance construction materials and protection systems, are available to implement cost-effective repair programs. These repair programs can extend service life and protect the value of the high initial investment associated with the construction of hyperbolic natural draft cooling towers.
