Materials and Methods of Corrosion Control of
Reinforced and Prestressed Concrete
Raymond Ehrhard, P.E.
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.
