Download or read book Evaluation of Corrosion Protection Methods for Reinforced Concrete Highway Structures written by Jennifer L. Kepler and published by . This book was released on 2000 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the 1970s, research projects and field studies have been conducted on different methods for protecting reinforced concrete bridges from corrosion damage. The methods include alternative reinforcement and slab design, barrier methods, electrochemical methods, and corrosion inhibitors. Each method and its underlying principles are described, performance results of laboratory and/or field trials are reviewed, and systems are evaluated based on the results of the trials. Using performance results from the studies and costs obtained from transportation agencies, an economic analysis is used to estimate the cost of each system over a 75-year economic life using discount rates of 2%, 4% and 6%.

This book was released on 2011 with total page 522 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The performance of corrosion protection systems for reinforcing steel in concrete is evaluated. In addition to conventional and conventional epoxy-coated reinforcement, the corrosion protection systems tested include epoxy coatings with improved adhesion to the underlying steel, conventional and conventional epoxy-coated reinforcement used in conjunction with concrete containing one of three corrosion inhibitors, DCI-S, Rheocrete 222+, or Hycrete, epoxy-coated reinforcement with a microencapsulated calcium nitrite primer, multiple-coated reinforcement with a layer of zinc between the epoxy and steel, and pickled 2205 duplex stainless steel. The systems are evaluated using bench-scale and field tests. Two bridges in Kansas, cast with 2205 stainless steel, are monitored using corrosion potential mapping. Epoxy-coated and multiplecoated bars are evaluated to determine the effect of corrosion loss and time on the disbondment of the epoxy coating. Conventional, galvanized, and epoxy-coated reinforcement are evaluated using impressed current to determine the corrosion loss required to crack concrete for each system. A finite element model is developed to represent general and localized corrosion, and the results are used to develop a relationship between concrete cover, bar diameter, and area of bar corroding, and the corrosion loss required to crack concrete. An analysis of pore solutions expressed from cement pastes containing corrosion inhibitors is performed, with pH and selected ion concentrations measured from solutions collected one and seven days after casting. The results obtained from bench-scale and field test specimens are used to estimate cost effectiveness for each system under a 75-year service life. The results show epoxy coatings significantly reduce the corrosion rate compared to conventional reinforcement. Corrosion inhibitors significantly reduce corrosion rates in uncracked concrete. In cracked concrete, corrosion inhibitors also reduce corrosion rates, but their relative effectiveness is reduced. Specimens containing Hycrete exhibit the lowest corrosion rates; however, field specimens containing Hycrete also show signs of scaling. Epoxies with improved adhesion exhibit no improvement over conventional epoxy-coated reinforcement in terms of corrosion rate or disbondment of the epoxy coating. Multiple-coated reinforcement exhibits significantly less disbondment than epoxy-coated reinforcement. Pickled 2205 reinforcement exhibits the least corrosion among all systems tested. Testing of conventional and galvanized reinforcement indicates galvanized reinforcement requires more than twice as much corrosion loss to crack the surrounding concrete compared to conventional reinforcement."--Technical report documentation page.

This book was released on 2004 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive research investigation was conducted to evaluate the use of Stay-in-Place Metal Forms(SIPMFs) in construction of concrete bridge decks. The objectives of this research project were to establish the state-of-the-practice for use and performance of SIPMFs for bridge decks, to evaluate the field performance of bridge decks with and without SIPMFs, and to investigate the behavior of environmentally conditioned large-scale laboratory bridge deck specimens with and without SIPMFs.

This book was released on 1995 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the U.S., epoxy coated reinforcing steel has been used extensively in bridge construction for over 15 years. Major studies over the last five years or so have examined past and current practices on the use of epoxy coatings to prevent corrosion of reinforcing steel. These studies and the experiences of some state highway agencies indicate a postential for less service life than previously expected. consequently, it is projected that a methodologoy will be needed to evaluate the corrosion condition of bridge structures containing epoxy coated reinforcing steel. As in the case of bridge structures with black reinforcement, a properly conducted corrosionn condition survey provides the information required to select appropriate repair and/or rehabilitation strategies.

This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research program develops and validates structural design guidelines and details for concrete bridge decks with corrosion-resistant reinforcing (CRR) bars. A two-phase experimental program was conducted where a control test set consistent with a typical Virginia Department of Transportation bridge deck design using Grade 60 steel (ASTM A615, fy = 60 ksi) and epoxy-coated reinforcing steel was compared to deck slab specimens where Grade 60 is replaced with CRR bars. The experimental program was designed to evaluate how flexural performance at service and ultimate limit states are affected by a one-to-one replacement of Grade 60 with CRR bars, a reduction of concrete clear cover, and a reduction in rebar size. Structural analysis models were developed using Response 2000 in order to predict the CRR bridge deck moment-curvature and the moment-crack width relationships. Experimental trends proved to be consistent with the analytical results demonstrating the viability of Response 2000 as a design tool for reinforced concrete with high-strength and nonmetallic rebar without a defined yield plateau. For reduced bar size and clear cover (2.00 in instead 2.50 in), ASTM A1035 and UNS S32304 specimens proved to have similar deformability ratios and crack widths that comply with current AASHTO requirements, with as much as 36% less steel.
