Download Factory Applied Corrosion Protection of Prestressing Steel Book in PDF, ePub and Kindle
Without doubt, active corrosion protection of prestressing steels by cement grout can be one of the most economic and durable solutions, if properly executed. Numerous other corrosion protection systems which fulfill requirements such as controllability and exchangeability are available. This state-of-the-art report, prepared by a task group and approved by fib Commission 9 Reinforcing and prestressing materials and systems, concentrates exclusively on factory applied corrosion protection that can be produced in controlled processes which should assure a better quality than corrosion protection applied on site. The report is addressed to designers and installers (executing persons) attempting to inform them about the various possibilities for industrially applied corrosion protection and to provide the necessary knowledge for their application.

This is the final report in a study to demonstrate the feasibility of using cathodic protection (CP) on concrete bridge structures containing prestressed steel. The interim report, FHWA-RD-95-032, has more details on the installation of selected CP systems. Past laboratory and test yard studies had indicated that overprotection could result in the evolution of atomic hydrogen and the embrittlement of prestressing steel. Systems utilizing catalyzed titanium mesh, conductive rubber, and arc-sprayed zinc anodes were installed on prestressed pilings and girders of the Howard Frankland Bridge in Tampa, Florida; and systems using flame-sprayed zinc and conductive paint anodes were installed on the soffit of prestressed box beams of the Abbey Road and West 130th Street bridges near Cleveland, Ohio. For most of the components tested, CP was achieved safely and reliably without reaching conditions that could result in embrittlement of prestressed steel.

Recognizing the burden that reinforcing steel corrosion imposes on natural resources, the Federal Highway Administration established Corrosion Protection for Concrete Bridges as one of the high-priority areas (HPAs) in its Structures Research Program. This report summarizes the progress made through research efforts conducted under these programs. The results presented cover (A) corrosion control in new concrete constructions (adequate concrete cover, quality concrete, rebar coatings, corrosion inhibiting admixtures, and corrosion protection of prestressed concrete bridge members) and (B) corrosion control for rehabilitation of existing concrete structures (conventional rehabilitation methods, cathodic protection, and electrochemical removal of chloride).

Download Survey of Costs, Economic Analysis, and Design Guidelines for Corrosion Protection Methods for Post-tensioned Concrete Bridges Book in PDF, ePub and Kindle
At the design stage, engineers and owners have the most influence on the future durability of post-tensioned concrete bridges. Yet design guidelines are not clear on what corrosion protection methods are appropriate for a given exposure environment. Current specifications do not ignore corrosion protection. However, many simply instruct the designer to protect the anchorage and prestressing steel from corrosion, leaving the selection of the appropriate method to the engineer’s experience. As well, many decision-makers do not have a good understanding of how post-tensioning works, how it can be protected from corrosion, or how much it will cost to increase the durability of the posttensioning system. This thesis includes a description of post-tensioning systems and corrosion protection methods as a reference for those not intimately familiar with the mechanisms and protection approaches. It gives the results of an industry cost survey that shows the expected cost increases, as a percentage of total initial construction cost, from including corrosion protection in the design. As well, life cycle analyses for several methods show their potential to save the owner money over the bridge’s expected life. Additionally, this thesis examines several current or proposed design specifications for their corrosion protection guidance. A new combination of these guidelines is proposed to give a more logical and designer-friendly option

Download Investigation of Corrosion Protection Systems for Bridge Stay Cables Book in PDF, ePub and Kindle
The use of cable-stayed bridges in medium- and long-span applications in the United States has increased significantly in the past ten years. Of paramount importance with this type of bridge is the protection of the stay cables from corrosive elements. An extensive survey, reported herein, showed a general concern over the adequacy of the corrosion protection of the most widely used current system. In this study, the popular two-barrier system (prestressing strand inside polyethylene sheath injected with portland cement grout) was examined experimentally. The effectiveness of the grout in providing secondary corrosion protection in the event of a cut or break in the external sheathing was a major focus of the experimental work.
