Abstract:
For concretes used in applications with high levels of chloride exposure, special systems can be specified to increase concrete durability. These systems work by reducing the rate of ingress of chloride, increasing the chloride level at which corrosion initiates, or reducing the rate of corrosion at active corrosion cells. Once the performance of the available corrosion protection systems is quantified, computer models can be used to perform life-cycle cost analyses for selection the most cost-effective combinations. An example analysis is provided.
