Presents guidelines for cathodic protection of reinforcing steel in concrete structures. The guidelines are limited to impressed current cathodic protection systems for new or existing atmospherically exposed reinforced concrete and are not intended for application to prestressed concrete. Criteria described include 100 mV polarization development/decay, statistical distribution analysis, and E-log I analysis.
A corrosion management system (CMS) for assets is described in this Standard. The framework is intended to be applicable to a wide variety of asset types and is not focused on a particular industry or sector. Non-mandatory guidance is provided throughout this Standard to aid users with implementing the Standard. The framework in this Standard can be utilized to develop a stand-alone CMS or to integrate corrosion management into an organization’s existing management system. Additionally, some processes covered in this framework may already be implemented by an organization, for example, management of change (MOC). An organization may modify their existing processes to address the elements identified in this framework.
New in 2020! This standard presents accepted methods and practices regarding the use of cathodic protection (CP) for the control of external corrosion on buried or submerged carbon steel, stainless steel, gray cast iron, ductile cast iron, copper, and aluminum piping systems at nuclear power plants. This standard may be useful at facilities other than nuclear power plants that contain complex networks of buried or submerged piping, which may be composed of more than one material and may or may not be grounded.
Steel corrosion in concrete structures. Accelerated corrosion tests were performed periodically and the corrosion rates at different time intervals were measured with linear polarization resistance (LPR). The change in the resonant wavelength over time was recorded using an optical spectrum analyzer (OSA).
Adsorption/desorption process of 1-(2-aminoethyl)-2-oleyl-2-imidazolinium chloride on carbon steel. To study adsorption of imidazolinium chloride on carbon steel, in-situ atomic force microscopy measurements were performed in air, with and without imidazolinium chloride, in a 1 wt% NaCl solution purged with CO2 at pH 4.
