Chloride-induced corrosion of steel reinforcement is the main reason marine reinforced concrete (RC) structures deteriorate early. Conventional concrete cover does not give enough long-term protection against harsh marine conditions. This study investigates the multifunctional properties of ultra-high-performance concrete (UHPC) as an advanced protective coating material for RC, with a systematic evaluation of mechanical performance, microstructural characteristics, corrosion-protection efficacy, and self-sensing capability. UHPCs with varying water-to-cement ratios (W/C = 0.20 and 0.30) and steel fiber contents (0%, 0.5%, and 1.0 vol%) were utilized for coating RC under 120 days of accelerated electrochemical corrosion testing with and without pre-load. All UHPCs substantially outperformed RC, with steel mass loss ratios reduced from 74.09 to 100% in RC without UHPC coating to as low as 0.51% in RC with UHPC coating containing 1.0 vol% steel fibers, because the microstructural densification of UHPC coating substantially reduces Cl- ion penetration. The addition of steel fiber is identified as the most influential parameter on the corrosion protection of UHPC coating. Furthermore, UHPC with 1.0 vol% steel fiber shows a clear piezoresistive response under compression, indicating preliminary potential for self-sensing applications.
