This NACE standard presents guidelines for cathodic protection (CP) of reinforcing steel in buried or submerged concrete structures. These guidelines provide corrosion control personnel with information to control corrosion of conventional reinforcing steel in portland cement concrete structures through the application of CP. The guidelines presented in this standard are limited to CP systems for new or existing buried or submerged reinforced concrete elements.
This updated NACE International standard test method specifies test methods to evaluate the performance of liquid coating systems for seawater immersion services. This test method is intended for use by facility owners and coating manufacturers.The test method covers liquid exterior protective coating systems for offshore platform steel structures, piers, docks, pilings, subsea valves, and wellheads at normal seawater temperature.
Included are four test methods—including cathodic disbondment, seawater immersion resistance, aging stability, and edge coverage—used to evaluate coating systems. The test method also includes two tables; Table 1 details fingerprinting of coating materials, and Table 2 details the test panel geometry, size, substrate material, and minimum quantity.
This technical report presents state-of-the-art information on several commercially available galvanic cathodic protection/prevention systems for protecting atmospherically exposed reinforced concrete structures. The information contained in this report has been provided by key manufacturers of these systems and is intended as a technical resource for engineers responsible for the rehabilitation of reinforced concrete structures. It may also be useful to owners, contractors, and other practitioners related to the field of galvanic cathodic protection (CP). All information related to galvanic CP is intended for atmospherically exposed concrete structures and may not be applicable to concrete containing epoxy-coated reinforcing steel, galvanized, or other coated or nonferrous reinforcement.
This technical report presents evaluation techniques which can potentially be used to complement performance criteria of international standards, especially if the criteria cannot be employed to evaluate the effectiveness of cathodic protection and corrosion control techniques applied to existing reinforced concrete structures, including atmospherically exposed, buried, and submerged structures.
This report is intended to be useful to architects, structural engineers, architectural conservators, and consulting engineers/contractors who are engaged in refurbishing steel-reinforced concrete structures and buildings.
