Overview
Salt-induced reinforcing steel corrosion in concrete bridges has undoubtedly become a considerable economic burden to many State and local transportation agencies. Since the iron in the steel has a natural tendency to revert eventually to its most stable oxide state, this problem will, unfortunately, still be with us, but to a much lesser degree due to the use of various corrosion protection strategies currently used in new construction. The adoption of corrosion protection measures in new construction, such as the use of good design and construction practices, adequate concrete cover depth, low-permeability concrete, corrosion inhibitors, and coated reinforcing steel, is significantly reducing the occurrence of reinforcing steel corrosion in new bridges.
This study report summarizes the results of various research investigations in developing and evaluating the performance of various corrosion protection systems. This report describes materials and measures that can be used for corrosion control in reinforced and prestressed concrete bridge structures in new construction. This report will be of interest to materials and bridge engineers, reinforced concrete corrosion specialists, and those concerned with the performance of reinforced and prestressed concrete bridges.
The course follows the report. The exam for this course contains multiple choice questions and several true and false questions.
The student is expected to read and review the material contained in; Materials and Methods of Corrosion Control of Reinforced and Prestressed Concrete Structures in New Construction, U.S. Department of Transportation, Federal Highway Administration
The student must take a multiple-choice quiz consisting of forty (40) questions at the end of this course to obtain 8 PDH credits.
