Concrete Durability

Evaluating the performance of corrosion protection systems requires an understanding of corrosion mechanisms as well as the protection mechanisms. The evaluation process is made more difficult by the fact that no single accelerated testing technique can be used for all systems. Once the performance of the available corrosion protection systems are quantified, however, it is possible to perform a life-cycle cost analysis to select the most cost effective system. This life-cycle cost analysis considers not only the costs for the corrosion protection system but also the costs associated with repairs and loss of use. This article provides an example of such an analysis that considers the type of concrete, the type of reinforcement and the amount and type of admixtures. Using a life cycle analysis program, a bridge deck exposed to deicing salts was modeled, and initial and total net present values were calculated for various design cases. Studies indicate that good quality and low permeability concrete produced using corrosion-inhibiting and shrinkage-reducing admixtures can provide the most cost effective solutions.
