Download or read book Effectiveness of Epoxy-coated Reinforcing Steel - Interim Report written by and published by . This book was released on 1992 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary function of an epoxy coating is to act as a barrier to prevent corrosion-causing chloride ions and oxygen from reaching steel surfaces. For more than a decade, epoxy-coated reinforcing steel has generally been effective in reducing or preventing chloride-induced corrosion in bridges and other concrete structures. Recently, however, instances of corrosion problems or premature failures in Florida, Oregon and New York have focussed attention on the product and its quality. This report was initiated as a result of the questions raised by these failures. In the first section of the report, a state of the art review of epoxy-coated reinforced steel is presented. It details the research performed on epoxy coating, and the results of this research both in the lab and in the field. As well, the authors highlight several areas to be considered for future investigation. The second section examines the fundamentals of epoxy, and the coating process. It provides an overview of the theory, technology, testing and practice as these presently exist for fusion bonded epoxy coatings on steels. The significance of the tests available for use on epoxy-coated rebars and epoxy-coated pipe is described. The report contains numerous figures.

Pyć and published by . This book was released on 1998 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: We used a simulated concrete pore water solution to evaluate the corrosion protection performance of concrete corrosion-inhibiting admixtures and epoxy-coated reinforcing bars (ECR). We evaluated three commercial corrosion inhibitors, ECR from three coaters removed from job sites, one ECR shipped directly from the coater's plant, and one ECR removed from a job site plus a corrosion inhibitor. The corrosion inhibitors were calcium nitrite, an aqueous mixture of esters and amines, and a mixture of alcohol and amine. Corrosion protection performance was based on the amount of visually observed corroded surface area. For bare steel tested with and without corrosion inhibitors, corrosion increased with increasing chloride concentration, and specimens saturated with oxygen were more corroded than specimens saturated with breathing air. The amount of corrosion over the 90-day test period was controlled by the amount of oxygen in solution at the higher chloride concentrations. The ester-amine and alcohol-amine did not inhibit corrosion. Calcium nitrite inhibited corrosion at all levels of chloride concentration. For ECR, corrosion occurred both at sites where the coating was damaged and underneath the coating. Coating debondment was greatest in pore water solutions containing chloride. The least coating debondment and corrosion occurred in the solution containing calcium nitrite and the ECR shipped directly from the manufacturer. Coating debondment and corrosion of ECR are directly related to the amount of damage as holes; mashed, dented, and cracked areas; and holidays. The researchers recommend that the developed test method be adopted as a standard test for concrete corrosion inhibitors and that calcium nitrite remain the only concrete corrosion inhibitor approved for use in Virginia.

Book Synopsis Effect of Cathodic Protection on Epoxy-coated Rebar by : S. Ray Taylor
Download or read book Effect of Cathodic Protection on Epoxy-coated Rebar written by S. Ray Taylor and published by . This book was released on 1998 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: Epoxy coating is widely used to mitigate the access of chloride ions to the surface of a rebar. However, corrosion at the point of physical defects in the coating necessitates rehabilitation. Based on its effectiveness in mitigating corrosion of uncoated rebars, we examined cathodic protection (CP) as a method for rehabilitating epoxy-coated rebars (ECR). Although it is well established that cathodic polarization of epoxy coatings on steel in aqueous conditions leads to disbondment of the coating, neither the conditions that lead to this phenomenon nor the actual occurrence of this disbondment process has been determined for ECR in concrete. Since the integrity of the bond between the rebar and the concrete is essential to the composite strengthening by the rebar, the relationships among CP, the integrity of the epoxy coating, and the strength of the rebar/concrete bond must be investigated. The objectives of this study were (1) to determine if CP can effectively mitigate corrosion of coated rebar without adversely affecting the rebar/concrete interface, and (2) to examine the effect of cathodic polarization on the disbonding characteristics of the epoxy coating/rebar interface in concrete. Fifty-five samples of No. 5 ECR with coating defects were exposed to CP. Tensile loading produced splitting failures of all samples. This mode of failure allows greater sensitivity to the contributions of concrete/rebar adhesion and friction than do pullout failures. All electrochemical tests indicated that the cathodic polarization levels and times of application used in this study were effective in preventing corrosion of embedded ECR. An important finding was that the CP protection levels and times had no effect on the splitting failure characteristics based on comparisons of 95 percent confidence intervals. Multiple parameters within the electrochemical impedance spectra indicated that the epoxy coating was delaminating from the steel at the periphery of the defects. This phenomenon was verified in a post mortem analysis of the samples using scanning electron microscopy. The immediate significance of this result is that CP current demands could increase over time. Even though the levels of delamination in this study did not affect mechanical performance, a protective CP level that does not induce film delamination should be explored.

Available in PDF, EPUB and Kindle. Book excerpt: Methods for reducing the corrosion of reinforcing steel in concrete in the presence of deicing salts are evaluated and developed. An electrochemical laboratory study was conducted since it was conjectured that corrosion resulted from the interactions between different galvanic cells, and investigations were made of corrosion inhibitors to be added to deicing salts, metallic and nonmetallic coatings for the reinforcement and cathodic methods of protection. Four metallic coatings were studied - copper, nickel, zinc, and lead.
Book Synopsis Corrosion Inhibitors for Steel in Concrete by : Bernhard Elsener
Download or read book Corrosion Inhibitors for Steel in Concrete written by Bernhard Elsener and published by CRC Press. This book was released on 2001 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of inhibitors for rehabilitation of reinforced concrete structures is a new field of application and this new volume provides a State of the Art Report on this subject. Corrosion of steel in concrete is one of the major problems for infrastructure such as bridges, tunnels, housing etc. since it leads to spalling of the concrete and loss in cross section of the steel that may cause structural and safety problems. The steel in concrete generally resists corrosion as a result of a passive layer that develops on the metal surface in the alkaline environment of the concrete. Corrosion can occur if these conditions are disturbed, for example, in the presence of chlorides or with carbonation of concrete. Traditional repair methods consist in removing the deteriorated concrete and replacing it but these can be laborious, noisy and very costly. To avoid these disadvantages new methods have been developed in recent years. These include electrochemical procedures and, increasingly, the use of inhibitors. The use of inhibitors for rehabilitation of reinforced concrete structures is a new field of application and this new volume provides a State of the Art Report on this subject.The report, under the editorship of Prof. Bernhard Elsener, was prepared by a Task Group of the EFC Working Party on Corrosion of Reinforcement in Concrete. In a literature review it describes inorganic and organic chemicals that have been proposed and examined as well as the commercial corrosion inhibitors that are available on the market. Protection mechanism and possible effects of inhibitors on concrete properties are described. Practical experience with inhibitors for steel in concrete and the long term effectiveness are considered. The various test methods for evaluating the behaviour of the inhibitors are described and critically assessed. In a rapidly evolving field this State of the Art Report, based mainly on independent not commercial literature, will be of value to corrosion engineers and civil engineers concerned with maintenance and repair of reinforced concrete structures.
