Download or read book Cathodic Protection Field Trials on Prestressed Concrete Components, Final Report written by and published by . This book was released on 1998 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Long-term Effects of Cathodic Protection on Prestressed Concrete Bridge Components by :
Download or read book Long-term Effects of Cathodic Protection on Prestressed Concrete Bridge Components written by and published by . This book was released on 1998 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: While cathodic protection effectively reduces or stops ongoing corrosion of reinforcing steel in concrete, applicability of this technology to prestressed members has been limited because of concerns regarding possible bond loss and hydrogen embrittlement. Within this context, the present research was intended as a comprehensive, multifaceted undertaking to elevate the understanding of prestressed concrete cathodic protection to the same level as for reinforced concrete. The program involved four components: (1) constant extension rate testing (CERT) of precorroded tendon wires, (2) cathodic overprotection of precorroded, pretensioned beams with evaluation for hydrogen embrittlement susceptibility, (3) concrete block pull-out tests to determine any effect of cathodic protection on the tendon-to-concrete bond, and (4) evaluation of a commercially available remote monitoring and control hardware and software system for application to prestressed concrete cathodic protection.

Book Synopsis Corrosion of Steel in Concrete by : John P. Broomfield
Download or read book Corrosion of Steel in Concrete written by John P. Broomfield and published by CRC Press. This book was released on 2023-01-31 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: Corrosion of Steel in Concrete: Understanding, Investigation and Repair is a guide for designing, constructing and maintaining reinforced concrete structures, such as buildings and bridges which are subject to reinforcement corrosion. It presents the basics of theory and practice in steel corrosion in concrete and reviews the latest research and developments, such as progress on measuring the corrosion threshold for chloride-induced corrosion. This third edition compares the currently proliferating major national and international standards and guidance documents. New developments are considered, such as hybrid anodes for electrochemical treatment and the latest research and developments in assessment, such as the use of ground penetrating radar to measure the chloride content of the concrete cover. It overhauls coverage of electrochemical repair and rehabilitation techniques and outlines recent innovations in structural repair and construction and investigates their implications for durability. The book is ideal for practitioners and graduate students in structural engineering and concrete technology.
Book Synopsis Cathodic Protection Developments for Prestressed Concrete Components by : M. Funuhashi
Download or read book Cathodic Protection Developments for Prestressed Concrete Components written by M. Funuhashi and published by . This book was released on 1994 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the final report in a study that evaluated the feasibility of using cathodic protection on prestressed concrete bridge members. Four pretensioned beams were constructed. In addition, two post-tensioned slabs were constructed to evaluate the ability of cathodic current to provide corrosion protection to anchorages and tendons encased in metal or plastic conduits. Cathodic protection currents were supplied by IR drop-free potential controlled rectifiers. Later in the study, constant-current power supplies were utilized.

Download or read book Cathodic Protection Developments for Prestressed Concrete Components written by and published by . This book was released on 1993 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of cathodic protection on the embrittlement of high strength steel embedded in concrete were studied. The results show that cathodic protection will generate hydrogen on the steel if the potential is more negative than the thermodynamic hydrogen evolution potential. The atomic hydrogen generated will enter the steel and cause a loss in ductility which will adversely affect the steel's performance if a notch is present. Studies are continuing on full-scale beams to study this effect and effective cathodic protection criteria. Conductive paint anode systems were tested to shed light on the causes of anode deterioration. Anode disbondment is largely the result of acids generated between the anode and concrete interface. Studies are continuing on several methods to improve the long-term bond strength between the anode and concrete.
