This book was released on 1993 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: This manual is a practical guide for state highway agency personnel who are faced with the day-to-day task of cost-effectively protecting repairing, and rehabilitating concrete bridges exposed to chloride laden environments. The manual addresses the chloride induced corrosion of reinforcing steel. Methods are presented to estimate the service life and remaining service life of concrete bridge components. Economic models are presented to enable selection of the most cost effective methods. These methods include standard physical, chemical, and experimental protection, repair, and rehabilitation. Also, rapid bridge deck protection, repair, and rehabilitation methods are presented. Two mechanized concrete removal methods, milling and hydrodemolition, are compared to the traditional method, pneumatic breakers. The advantages of combining the strengths of the three removal methods are also presented.

Purvis and published by Strategic Highway Research Program (Shrp). This book was released on 1994 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: A systematic methodology is presented for highway agencies to use at the project level to determine the most cost-effective treatment, and its timing, for specific concrete bridge components that are deteriorating or are subject to deterioration. The methodology is set forth in the form of both a handbook and a computer program. The methodology in its present form applies only when the predominant concrete deterioration is associated with chloride-induced corrosion of the reinforcing steel. The methodology is designed to be flexible and can be tailored to suit the needs of individual highway agencies.

Download or read book Long term Performance of Corrosion Inhibitors Used in Repair of Reinforced Concrete Bridge Components written by Moavin Islam and published by DIANE Publishing. This book was released on 2003 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary objective of the project was to determine the effectiveness of cathodic protection, electrochemical chloride extraction, and corrosion-inhibitor treatment systems installed during the SHRP effort through the long-term evaluation of 32 field test sites and a number of laboratory concrete slab specimens. The FHWA program required monitoring the long-term performance of corrosion inhibitor treatments on selected components of four bridges that were treated and evaluated under SHRP C-103. Three evaluations over a period of 5 years were conducted on structures located in Minnesota, New York and Pennsylvania, and two evaluations were conducted on a structure in Washington State. An analysis of the results concluded that neither of the corrosion inhibitors evaluated in this study, using the specified repairs and exposed to the specific environments, provided any corrosion-inhibiting benefit. Shrinkage cracking plagued repairs at all test sites except for the Washington site.

Available in PDF, EPUB and Kindle. Book excerpt: This report presents a study on estimating the service life cycle of reinforced concrete bridge components exposed to chloride-laden environments. Current treatment options are identified and an opinion survey was used to obtain first estimates of service life. To estimate the service life of untreated and rehabilitated bridge decks, data from 52 bridge decks distributed in different environmental conditions were collected. Models estimating the service life of untreated and rehabilitated bridge decks were developed and compared with models developed based on historical data and the time-to-rehabilitate model.

Download or read book Concrete Bridge Protection and Rehabilitation written by and published by . This book was released on 1993 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study examined and developed feasible chemical methods for the corrosion protection of reinforcing steel in concrete bridges. A broad spectrum of chemicals were evaluated: corrosion inhibitors, chloride scavengers, and polyaphrons. Inhibitors were evaluated and recommendations were made. Reinforced concrete specimens were cast and subjected to repeated exposure to sodium chloride solution and evaluated to investigate the inhibitors effectiveness after removing contaminated concrete. Corrosion progress was monitored. Polyaphrons were investigated as a possible corrosion preventor/reducer inhibitor. Based on results, polyaphrons are not recommended as a practical concrete bridge treatment.

This book was released on 1999 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes a technology review, field surveys, and laboratory investigations into the corrosion of prestressed concrete highway bridge elements and conventional repair methods used for these structures. Details of the technology review and field surveys are given in an Interim Report (FHWA-RD-95-041). Subsequent to completion of the field surveys, a laboratory program designed to evaluate corrosion performance of conventional concrete repair materials was initiated. Test specimens were precorroded by application of anodic current while exposed to chloride solutions. In order to study conventional concrete repairs, it was necessary to remove concrete from preselected areas on each purposely corroded test specimen and replace the chloride-contaminated/deteriorated original concrete with repair materials. Materials evaluated included conventional portland cement concrete, latex-modified fiber-reinforced patching mortar, and silica fume concrete containing either organic or inorganic corrosion inhibitors. Specimens where concrete was not removed were used to study the effects of sealers and coating applied on concrete surfaces to mitigate ongoing corrosion. All specimens were exposed for approximately 200 weeks to a 15% solution of sodium chloride after repair. At the conclusion of exposure, patches were removed from repair specimens and the steel and the applied coatings were examined.

Download or read book Bridge Rehabilitation written by Radomski Wojciech and published by Imperial College Press. This book was released on 2002-10-28 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last two decades, the rapid deterioration of bridge structures has become a serious technical and economical problem in many countries, including highly developed ones. Therefore, bridge rehabilitation has also become a very essential factor (sometimes even a decisive one) in contemporary bridge engineering. The book covers in synthetic form nearly all the most important problems concerning bridge rehabilitation, such as bridge superstructure and substructure, the typical damage observed in bridges as well as the assessment and evaluation techniques of their technical condition. The book is intended mainly for postgraduate university students. Therefore, all the problems are mostly presented in their physical, chemical and technical as well as economical aspects. The relevant requirements are treated as objective ones, i.e. irrespective of the rules, standards, regulations or guidelines particular to any country. This approach to the subject gives the book a more general character and therefore makes it a useful text for most civil engineering courses./a
