CONCRETE REPAIR AND PROTECTION WITH CORROSION INHIBITOR

Corrosion is estimated to cost the United States $250 billion annually. Corrosion of reinforcing steel in concrete structures represents a significant portion of that cost. Given the current age and general status of our nation's concrete infrastructure, it is important that cost effective means of controlling this complex problem and extending the service life of these structures be identified and implemented. Many different approaches to concrete repair and protection exist. Each structure must be evaluated to determine which approach is most feasible for meeting the requirements of the owner. For 50-year protection of a structure that cannot be replaced, perhaps cathodic protection is the only alternative (costly though it may be). To protect a structure for five years until it can be demolished and replaced, a less expensive option is more appropriate. Within this spectrum of options, corrosion inhibitors can now be evaluated in terms of a cost vs. performance basis. And for concrete repair and protection against corrosion, they offer some new options that may prove valuable in many situations.
