Corrosion Behavior Of Steel In Deficient Grout With Enhanced Sulfate Ion Concentrations, Krishna Vigneshwaran Konda Krishnamurthy Apr 2016

Corrosion Behavior Of Steel In Deficient Grout With Enhanced Sulfate Ion Concentrations, Krishna Vigneshwaran Konda Krishnamurthy

FIU Electronic Theses and Dissertations

Recent corrosion failures of tendons in Florida post-tensioned (PT) bridges utilizing low bleed specified grout products have shown the need for better understanding of the mechanisms that cause corrosion and to determine the extent of the problem in PT tendons with similar materials. Those deficient grouts in the tendons showed low chloride content below commonly assumed threshold limits for corrosion initiation, but they showed higher concentrations of sulfate ions, high pore water pH and higher moisture content. The role of enhanced sulfate ion concentrations in the development of steel corrosion in deficient grout has not been elucidated, but the role ...


Vertical Drain Consolidation With Piecewise Linear Surcharge And Vacuum, Rohan Walker Jan 2013

Vertical Drain Consolidation With Piecewise Linear Surcharge And Vacuum, Rohan Walker

Faculty of Engineering and Information Sciences - Papers: Part A

Maintaining the simplicity of Hansbo's (1981) solution, this paper presents radial consolidation equations that capture some of the versatility of more complex analytical solutions. Material and geometry properties may vary piecewise-constant with time while loading/unloading, both surcharge and vacuum, may vary piecewise-linear with time. The new equations are easily implemented in a spreadsheet or computer program providing a simple yet versatile tool for analysis of consolidation problems dominated by radial drainage. Computer code for implementing the new approach in Microsoft Excel is provided
