This book was released on 1996 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: Whatever his name or alias at the moment—Henry McCarty, Henry Antrim, Kid Antrim, Billy Bonney—people always called him the Kid. Not until his final month did anyone call him Billy the Kid. Newspapers pictured him as a king of outlaws; and his highly publicized capture, trial, escape, and end fixed his image in the public mind for all time. He was only twenty-one years old when a bullet from Sheriff Pat Garett’s six-shooter killed him on July 14, 1881. Within a year Billy the Kid became the subject of five dime-novel “biographies” as well as Garett’s ghost-written account, and that was just the beginning. Robert M. Utley does what countless books, movies, television shows, musical compositions, and paintings have failed to do: he successfully strips off the veneer of legendry to expose the reality of Billy the Kid. Using previously untapped sources, he presents an engrossing story—the most complete and accurate ever—of a youthful hoodlum and sometime killer who found his calling in New Mexico’s bloody power struggle known as the Lincoln County War. In unmasking the legend Utley also tells us much about our heritage of frontier vigilantism and violence.

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.

Download or read book Time-to-corrosion of Reinforcing Steel in Concrete Slabs written by Yash Paul Virmani and published by . This book was released on 1983 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thirty-one relatively large reinforced concrete slabs were fabricated in 1980 using either non-specification epoxy-coated reinforcing steel or calcium nitrite admixture with black (uncoated) steel. Their performance is compared with uncoated steel in concrete without admixtures. The slabs were placed in two lifts: the bottom lift consisted of a bottom mat of reinforcing steel in chloride-free concrete; and a top lift consisting of the top-mat rebars in concrete contaminated with various quantities of sodium chloride. All the electrical connections between the reinforcing mats were made exterior to the slabs so that the corrosion current flow could be monitored. A worst case type of research design was used by specifying poor quality concrete, nonspecification epoxy-coated rebars, and good electrical coupling between the rebar mats. After curing, the slabs were mounted above ground and exposed to the environment of the Washington, D.C. location.

Book Synopsis Evaluating the Effect of an Alternative Epoxy Coating on Bond of Steel Reinforcing Bars by : Justin Sell
Download or read book Evaluating the Effect of an Alternative Epoxy Coating on Bond of Steel Reinforcing Bars written by Justin Sell and published by . This book was released on 2011 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report focuses on the effect an alternative polyurethane coating has on the bond performance compared with plain rebar. Twelve beam-end specimens were cast with six concrete specimens each containing one #8 plain reinforcing bar and six concrete specimens each containing one #8 coated reinforcing bar. Development length, cover depth, and presence of a coating were variables during testing. It was observed that coating thickness had the greatest effect on the overall strength capacity of the concrete specimens. The thick alternative polyurethane coating resulted in a strength decrease when compared to plain rebars. An increase in development length caused an increase in both strength and stiffness in coated and uncoated rebar. Concrete specimens with uncoated rebar saw an increase in capacity as cover increased but concrete specimens with coated bars saw a decrease in strength capacity.

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.
