New materials minimize effects of steel corrosion in reinforced concrete

摘要

Researchers with the National Center for Education and Research on Corrosion and Materials Performance (NCERCAMP) at the University of Akron (UA) (Akron, Ohio) are investigating the performance of several new materials that can be used to inhibit corrosion of reinforcing steel in concrete and enhance bond strength and resistance to cracking. The work is part of a project supported by the U.S. Department of Defense (DoD) Office of Corrosion Policy and Oversight that is modeling the corrosion of steel reinforcing bar (rebar) in concrete at various scales-from the micro- to the macroscale-to predict corrosion degradation and remaining strength of reinforced concrete structures.
