field and laboratory testing of epoxy-coated reinforcing bars in concrete Corrosion of reinforcement in concrete exposed to chloride-contaminated environments is a common problem. If the corrosion process proceeds undetected, the safety of the reinforced concrete structures may be by: 7. Epoxy coated steel reinforcement (ECR) was used for corrosion control in Florida DOT (FDOT) marine reinforced concrete bridges from the late ’s up to the early ’s. The use of ECR for new FDOT structures was discontinued upon mounting evidence of severe corrosion in some of the existing by: 4.

Page 6 of 15 Epoxy-coated bars can be used in structures with other reinforcing steel bars; however, when using epoxy-coated reinforcing steel in decks it is recommended that all the deck steel is coated as this will reduce the overall rate of corrosion if the coating is damaged.
In piers, the use of epoxy-coated reinforcing steel should be continued into an areaFile Size: KB. In reinforced concrete systems, ensuring that a good bond between the concrete and the embedded reinforcing steel is critical to long-term structural performance.
Without good bond between the two, the system simply cannot behave as intended. The bond strength of reinforcing bars is a complex interaction between localized deformations, chemical adhesion, and other factors.
In this study, the corrosion protection performance of epoxy-coated reinforcing steel (ECR) was evaluated using approximately concrete cores from 18 bridge decks in Virginia. The decks were 2 to 20 years old at the time of the investigation.
The deck field inspections. Epoxy-coated reinforcing steel has been used for over 40 years and is the most commonly used corrosion-resistant reinforcement used in concrete.
The first concrete deck was built inand currently overtonnes (, tons) of epoxy-coated reinforcing steel is. Over time, rebar that is exposed to deicing salts or marine environments can corrode. An epoxy coating protects reinforcing steel bars from corrosive conditions.
Epoxy coated rebar is ideal for bridges, parking structures, pavement, marine structures, and repair work. Re-Steel’s epoxy coating facility, Corrosion Control, Inc.

(FAQ) About Epoxy-Coated Reinforcing Bars Introduction The Concrete Reinforcing Field investigation of epoxy-coated reinforcing steel book Institute (CRSI) routinely receives inquiries concern-ing various aspects of reinforcing bars, and reinforced concrete design and construc-tion.
This Technical Note presents a col-lection of typical questions that are asked regarding epoxy-coated reinforcing bars. The manufacture of epoxy-coated reinforcing steel is covered by several ASTM standards including ASTM A, A, and A for reinforcing bars and A for welded wire fabric (mesh).
Bars manufactured to ASTM A are recognized by their green color, while bars manufactured according to ASTM A are either purple or grey. Burke, D. “Epoxy-Coated Rebar in Marine Concrete.” Military Engineer, _____ Dr. David McDonald is managing director of the Epoxy Interest Group and is based in Schaumburg, Ill.
Epoxy-coated reinforcing steel is commonly coated to meet ASTM A/AM, “Standard Specification for Epoxy-Coated Steel Reinforcing Bars.”. This chapter presents a consultant's perspective on galvanized steel reinforcement in concrete.
As noted through this book, reinforcement corrosion is a worldwide, multibillion dollar phenomenon. Some of the costs are discussed in more detail in the recent US study on the costs of corrosion.
As of January 1st,Metal Partners International is proud to announce a joint venture with Midwest Pipe Coating. This new venture will allow the synergies of two companies to come together as one. We are able to oversee every step of the process in real time, yielding better forecasting of epoxy products through controlled scheduling.
Corrosion processes and field performance of epoxy-coated reinforcing steel in marine substructures Book Saguees, A A ; Powers, R G ; Kessler, R Severe corrosion of epoxy coated rebar in the substructure of marine bridges in the Florida Keys has prompted an investigation of the condition of other bridges in the State.
The Epoxy Interest Group of CRSI is pleased to announce publication of a report on the performance of epoxy-coated bars in West Virginia. This study found that while the black bar decks were overlaid or otherwise rehabilitated after only 18 to 21 years to address deterioration of the deck surface, decks containing epoxy-coated reinforcing steel had not required repair after 33 years and the.
Investigation of Field Corrosion Performance and Bond/Development Length of Galvanized Reinforcing Steel Abstract In reinforced concrete systems, ensuring that a good bond between the concrete and the embedded reinforcing steel is critical to long-term structural performance.
Without good bond between the two, the system simply cannot behave as. The corrosion protection performance of epoxy-coated reinforcing steel (ECR) was evaluated in 18 concrete bridge decks in Virgina in The decks were 2 to 20 years old at the time of investigation.
The concrete bridge deck inspections included crack survey and. Section —Epoxy Coated Steel Reinforcement Page 2 4. The epoxy for the fabrication shop repair work shall also be suitable for use in the field by the Contractor installing the coated bars in the bridge deck. Fabrication 1.

Project studies for Bridges and Buildings produced using Epoxy Coated Rebar. Resources Publications, Presentations, Recent Papers, Reports, Specification & Field Practices, Archived Newsletters and. The objectives of this project were to: (1) investigate the field performance of epoxy-coated reinforcing steel in selected bridge decks in Pennsylvania and New York, (2) determine if ongoing or progressive corrosion and/or a reduction in coating adhesion were occurring, with a percent confidence level, in more than 3 percent of the deck.
FOREWORD. This report describes results obtained from a long-term natural weathering exposure testing of the remaining 31 post-Southern Exposure (SE) test slabs that contained epoxy-coated reinforcing bar (ECR), black bars, and stainless steel bars and were not autopsied during the – Federal Highway Administration (FHWA) research project.
