摘要：

The purpose of this study was to evaluate a proprietary (PUHPC) and non-proprietary (NPUHPC) UHPC mix for chloride ion penetration, freeze-thaw resistance, and scaling resistance to assess durability. Also, large-scale specimens were subjected to an impressed current to accelerate corrosion of embedded reinforcing steel to evaluate the severity of the potential for halo effect when using each concrete as a repair material for aged concrete. Each of the UHPC mixes outperformed conventional concrete in every test. Also, the PUHPC and NPUHPC had similar durability performance, and the NPUHPC outperformed the PUHPC in corrosion resistance, despite having a lower compressive strength.
