Abstract:

The U.S. Navy has developed and implemented new design and quality assurance procedures, including service life modeling of the concrete materials that improve the quality and durability of new marine concrete construction. The approach is delineated in the Uniform Facilities Guide Specification UFGS for Marine Concrete and is referred to as the Navys methodology. This approach allows Naval Facilities Engineering Command NAVFAC and others to specify a defined service life for concrete structures in combination with prescriptive criteria. The goal is to allow all parties involved in the design and construction process to have greater confidence that the completed structure will meet service life expectations. The cornerstone of this approach is a validated computer software program that can predict the time for chloride and other ions to contaminate the concrete to a degree that will result in initiation of corrosion when all other necessary conditions are met for a specific environmental condition. The purpose of this paper is to broaden exposure and to provide guidance on how to implement the methodology correctly and effectively for all users.
